ceph dashboard uses radosgw-admin for certain tasks that
aren't accessible via the rgw REST API. Due to the absence of
a valid ceph.conf file at /etc/ceph/ceph.conf within the mgr pod,
radosgw-admin fails to operate, resulting in 500 errors across
various 'Object Gateway' views on the dashboard. This change
adds CEPH_ARGS environment variable to the mgr pod enabling
its propagation and utilization by the dashboard/radosgw-admin
for executing rgw commands.

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.
Signed-off-by: Sébastien Han <seb@redhat.com>
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.

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.

This commit allows us to configure status check for each daemon:
* "mon": health check on the ceph monitors (quorum)
* "osd": health check on the ceph osds
* "status": ceph health status check
Each check is controlled by the following settings:
* disabled: whether to disable the check (default: false)
* internal: interval to run the check
* timeout: only valid for mons, is the timeout for unresponsive mon
before failling over.
Example to disable the status health check:
```yaml
healthCheck:
daemonHealth:
status:
disabled: true
```
As part of that, pod's livenessprobe can now be configured via the
following settings:
* disabled: whether to enable or not
* probe: override the current probe in place by a new one
```yaml

livenessProbe:
mon:

In any case, if Ceph resources are going to be restarted this must be
done carefully.
Also trimmed the isUpgrade variable, the upcoming commit will remove the
need of that variable.
Keeping isUpgrade from the controller code since we need it to detect
whether an orchestration upgrade should be triggered or not (based on
the ceph cluster status).
Also, we keep it on the child controllers so we don't go into an
orchestration phase if the cluster image hasn't changed. The child does
not need to be updated/go into its orchestration phase because the
cluster CR changed.

A new controller to bootstrap ceph-crash pod on Ceph nodes running Ceph
pods only.
This implementation is unfortunately a mix of 'hacks' to make the daemon
working correclty. The ceph-crash script faced different issues:
* it's not a daemon
* it does not have any key in cephx
* it runs ceph commands under the hood which need an admin key and a
ceph.conf
On upstream Ceph, ceph-crash needs to grow better, once that happens we
will improve our implementation.
This also enhances osd provisionConfig struct with DataPathMap
Pod volumes and volume mount needs DataPathMap to perform the right
actions on log and crash dir. Exposing DataPathMap makes that possible.
Obviously, this is exposing ceph crash reports on the host as
well as pushing them into the mgr.
Basically, if a daemon fails, it'll put its core dump into
/var/lib/ceph/crash, bindmounting this dir on the host, ensures that the
crashes don't get lost when the pod dies.
Example:

On rare occasion, the ceph checks might not be 100% correct and the user
might decide to force an upgrade anyway.
Correctly, if we are in an upgrade, we perform `ok-to-stop` check for

They are corner-cases where users would like to force the upgrade anyway.

It's quite convinient to expose /var/log/ceph so that we can decide to
activate logs locally on the machine and see what's going on.
This is only a placeholder when a daemon is stuck crashlooping and we
want to allow administrator to gather log files.
We still do not log on file but this can be activated via a config
option passed to the centralized config option store.
For some daemons, which typically do not store any data (rgw, rbd-mirror
and mds) we had to propagate dataDirHostPath from the cluster spec to
each creation call so that the bindmount can happen.
