the filesystem creation and configuration. Reversing the sequence lets
us avoid spurious FS_DOWN warnings when creating the filesystem.

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.

When mirroring is enabled on the filesystem, the status was not
being set on the filesystem. Now the reconcile will ensure the
status is updated on the CR whether or not mirroring is enabled.

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.

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.

Recently, the builds of `ceph/ceph` image moved to quay.io, see

Current images will remain but new builds will happen on quay.io only.
This means that tags such as `v14.2`, `v15.2`,`v16.2` will need to

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:
info:
fsMirrorBootstrapPeerSecretName: fs-peer-token-myfs
mirroringStatus:
daemonsStatus:
- daemon_id: 4186

We have been having many issues with external mode with Ceph version
mismatching. The operator would have a Ceph version different than the
external cluster. The `radosgw-admin` was used to interact with S3
users, even a small version delta would cause the command to coredump.
After checking with the rgw core team it appears Rook was misusing the
CLI and the admin ops API should be used instead.
So this patch is the first introduction of go-ceph in Rook to consume
the rgw admin ops API instead of the `radosgw-admin` CLI, **only** for
user management in this initial commit.
Later we can do more such as bucket operation, zone management etc.

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
what is needed for their storage provider instead of forcing to use the
same types and risk affecting another storage provider.

When deploying the ceph-fs-mirror daemon we don't need to name the
deployment like "rook-ceph-fs-mirror-a", we can simply go with
"rook-ceph-fs-mirror". Today, in Pacific, the daemon only supports a
single replica. In the future, the Ceph Quincy release should support
mulitiple concurrent daemons, at this point Rook will introduce a
"count" field in the CephFilesystemMirror CRD specification. Internally,
this field will map with the "replica" value of the Deployment.

By setting the working directory of a Ceph daemon to the log direcor
(which is bindmounted to the host), we can ensure that the coredumps
will be available.
On CentOS 7 **only**, the kernel is configured with:
```
cat /proc/sys/kernel/core_pattern
core
```
which means that the coredumps will end up in the process working
directory and will be named "core".
On CentOS 8, everything is different and this won't work but still
CentOS will be able to consume this and changing the working directory
is harmless.
