This commit is a large refactor on how the operator starts, stops and
how it starts various sub-components such as the ceph-csi driver. It
also refines the way we cancel orchestrations. We don't use breakpoints
anymore but send our self a SIGUP to reload our controller runtime
manager.
The reload will happen under different circonstances like:
* a new adminission controller secret is created/deleted/changed
* a CephCluster CR is edited
As mentioned earlier, the csi driver now has its own controller, just
like flex. It reacts to change in the operator config map for particular
ROOK_CSI_ fields.
A second new controller for the operator's general config has been
created, it manages:
* the logging level
* the ceph CLI command timeout
* the discovery daemon
The operator reacts much more rapidly to cancellation events by stopping
the manager's context and reloading it.

During disaster recovery/migration of a cluster, as part of the failover, the
kubernetes artifacts like deployment, PVC, PV, etc will be restored to a new
cluster by the admin. Even if the kubernetes objects are restored the
corresponding RBD/CephFS subvolume cannot be retrieved during CSI operations as
the clusterID and poolID are not the same in both clusters
This PR creates a mapping between Cluster ID and RBD Pool ID between
local cluster and peer cluster.

This handles the scenario where the OSDs have been created but not yet
started due to a wrong CR configuration.
For instance, when OSDs are encrypted and Vault is used to store
encryption keys, if the KV version is incorrect during the cluster
initialization the OSDs will fail to start and stay in CLBO until the
CR is updated again with the correct KV version so that it can start.
For this scenario, if the CRUSH map has no host registered yet it's fair
to assume the initialization broke and we need to fix it. So when don't
need to call ok-to-stop since it will always fail and eventually force
pass but let's not wait for nothing.

Trying to disable mirroring on a cluster where mirroring is not enabled
results in an error during upgrades. Let's catch this error and ignore
it.
Funny enough the exec error resembles to:
```
Error ENOTSUP: Module 'mirroring' is not enabled (required by command 'fs snapshot mirror disable'): use `ceph mgr module enable mirroring` to enable it: exit status 95
```
So we get ENOTSUP which is 45 but exit status 95...

They are scenarios where the mirroring information want to be shared
between clusters prior to creating pool. Because the bootstrap peer
import command needs a pool name to operate this is not suitable. So
additionally now each time the cluster is reconciled and on any new
clusters a new secret will be created that contains a boostrap peer
token. It can be exchanged with another cluster.

Instead of having the RBDMirroringPeerSpec in the RBDMirror CRD we want
to move it on the CephBlockPool CRD so that each pool can have its own peer.
This enables pool to re-use an existing peer secret if it points to the
same cluster peer.So we don't need to duplicate secret peer anymore.

Both `ExecuteCommandWithOutputFileTimeout()` and
`ExecuteCommandWithOutputFile()` generate unnecessary system calls by
creating/reading/removing files where the stream output of the command
can simply be used. So sticking with `ExecuteCommandWithOutput()` and
`ExecuteCommandWithCombinedOutput()` for reading outputs is sufficient.

Multiple filesystems are supported as of the Ceph Pacific release. So we
remove the flag from the operator configuration and just have a ceph
version check instead.
The Operator configuration option `ROOK_ALLOW_MULTIPLE_FILESYSTEMS`
has been removed in favor of simply verifying the Ceph version is
at least Pacific.
Multiple filesystems are stable since Ceph Pacific.
So users who had `ROOK_ALLOW_MULTIPLE_FILESYSTEMS` enabled will
need to update their Ceph version to Pacific.

We now pass the networking spec to the clusterInfo so that the executor
can make the right decision on how to execute a command.
This is a small change that allows us to remove the CephBlockPool CR
since it's checking for rbd images. On a Multus deployment, the operator
does not have the network annotations, thus has no access to the OSD
network then rbd commands are hanging forever.

The mon daemon in a stretch cluster now can have its location set

This enables mon failover to set the location of a mon immediately

When the CephCluster is configured with Multus and multiple networks are
used to deploy Ceph some commands are failing to be executed from the
Operator. These commands, in particular, `radosgw-admin` ones need access
to the "ceph public network" to talk to OSDs. Unfortunately, the
Rook-Ceph Operator does not have the network annotations and thus
doesn't have the networks available and cannot reach OSDs. So the commands end
up hanging and eventually time out.
Applying the annotations to the Operator pod is possible but will result
in restarting the operator too and this should be avoided at all costs.
Also, applying the annotations beforehand is not possible since the
Multus declaration is in the CephCluster specification. So we would have
no idea what to do.
So the current approach runs a new sidecar container in the mgr pod to
act as a proxy for "some" ceph commands, only the `radosgw-admin` ones
for multi-site setup. This is a small container with admin access
running idle waiting for commands to be executed. In a sense, it is
similar to the toolbox but we didn't want to clearly expose it, so
running as a sidecar is quite nice.
Proxying command is obviously not always recommended since we add an
extra hop in the network path. Now each request has to go from the
operator pod to the API server to the remote pod to Ceph. Previously,
the command only goes from the operator to Ceph.
It's worth noting that external mode is not impacted since no rgw pod
is configured. This scenario is flexible and allows us to scale
pretty well since any CephCluster with Multus will see its mgr sidecar
deployed and can then talk to Ceph. We are not limited.

Similarly to block volume replication, Ceph is capable of replicating the
content of a Ceph Filesystem from one cluster to another.
For this, during the 1.6 cycle, we introduced a new CRD called
CephFilesystemMirror which effectively deploys a cephfs-mirror daemon.
However, configuring peers to enable replication between two clusters
had to be done manually.
Also various bug fix made it in Ceph eventually and the minimum required
version for this to work is to run on Ceph Pacific 16.2.5 at least.
So the automatic configuration of Ceph Filesystem peers is now possible.
By editing the CephFilesystem CRD, you can now turn on mirroring:
```yaml
mirroring:
enabled: false
# list of Kubernetes Secrets containing the peer token
# for more details see: https://docs.ceph.com/en/latest/dev/cephfs-mirroring/#bootstrap-peers
peers:
secretNames:
- secondary-cluster-peer
```
Also, the mirroring status is displayed in the CR status:
```
status:

fsMirrorBootstrapPeerSecretName: fs-peer-token-myfs

- daemon_id: 4186

In the latest Ceph releases starting with v16.2.1, all clients are recommended
to be updated so they will have a security fix to connect with a secure
global ID. A health warning will be raised if any insecure clients are connected
and another health warning is raised if insecure clients are still allowed.
Rook will now disable allowing the insecure clients if the health warning
is not being raised to indicate that there are insecure clients still connected.
This means that upgraded clusters will not have this disabled until all the
daemons are updated.

The rook.io/v1 package was only an internal implementation detail and
does not have any CRDs that rely on it. The CRD deserialization should
handle the change in internal types without any issue. This separation
gives more flexibility for the storage providers to implement exactly

same types and risk affecting another storage provider.

A user with unbalanced system (e.g., some OSDs use a partition which
resides on a device along-side OS partition) may want to have a
fine-grained control on the overall load of specific OSD. While osd
weight affects write-load, primary-affinity affects read-load.
This patch allow user to define osd's primary-affinity (similar to
'DeviceClass' and 'InitialWeight'), which is sent to the osd (via mon)
as part of deployment sequence, using 'ceph osd primary-affinity' command.
Valid values are within the range [0.0, 1.0). If not set, default value
is 1.
