I don't know why these flags are there but it's not like we run the
operator with them and with a different value.
So removing for clarity.

earlier, we had the issue for osd placement regarding
whether we should merge the placements or not.
Now, we have option `skipApplyAllPlacement` to
enable/disable osd placement. By default it is false
which means it will merge both placement.All() and
storageClassDeviceSets.Placement, when true
it will only apply storageClassDeviceSets.Placement.
Also, adding unit test.

Also, small refactor to print nicely the list of remaining daemons.

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.

Recently, the builds of `ceph/ceph` image moved to quay.io, see
https://github.com/ceph/ceph-build/pull/1883 for more details.
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
switch to quay.io to get updates.

When there are multiple mgr daemons, the mgr sidecar owns reconciling
the services for the active mgr. However, for efficiency the sidecar
only reconciles the services if the active mgr changes. Now the operator
will also reconcile the mgr services to ensure that services are re-created
after being deleted, or otherwise in an incorrect state.

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
as a CLI param instead of setting it with a separate command.
This enables mon failover to set the location of a mon immediately
when it is joining quorum instead of having a delayed command
to set the location.

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.

If the reconcile is cancelled due to a CR update, we want to retry the next
reconcile immediately rather than wait for the exponential backoff timeout
if the reconcile was already failing. The wait can easily be minutes
if the reconcile was in this state, which makes it appear the operator
is ignoring the request to start a new reconcile.

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
filesystems:

In a production cluster we never should have two mons running on
the same node. However, if two mons have ended up on the same node,
whether from a bug or some other unintentional event, the operator
will evict one of them and failover to a new mon. This only applies
when allowMultiplePerNode is false.

When evaluating the potential "warning" key from the json output we were
not hiding stdout (1) from the output, so the key was leaked. Also the
warning check for the key was not perfect, it only checked for the
command to succeed, but we should introspect it since the "warning" key
is always present unlike the "error" one.
We now only print the warning or the error is present.

We have seen issues with fullchain.pem files containing one self-signed
certificate. At the same time, the failing configuration was not
providing any client certificates or keys.
The error from curl was `"self signed certificate in the chain"`.
The openssl binary is not available so we cannot even c_rehash the
certificate directory when using `--capath`, however this worked already
with a fully signed fullchain.pem along with a client certificate and
key. So we cannot only use `--cacert` which will break that use case.
This is becoming really obscur on why using `--cacert` solves this
problem. I just can't wait to use the `vault` binary, that's all I can
say...

When the mons are using the dataDirHostPath and not a volumeClaimTemplate,
they need to be permanently assigned to a node. The node assignment
was missing in stretch clusters when the dataDirHostPath was being
used. This resulted in mons that were moving to other nodes for example
during a node drain, which would cause the mon to lose its backing store.
