Refactor the Ceph NFS (Ganesha) daemon to use the new config pattern.
Use of a custom Rook binary to run NFS has been removed in favor of
instead running the required DBUS process as a sidecar. The effect here
is that the NFS Ganesha container itself may fail and restart a few
times before the DBUS sidecar is running.

We do not determine the daemon type and name by string parsing anymore
but passing that info directly in the update call, it's more reliable.
Also removing a bunch of unused functions.

Do not consider clusterInfo Ceph version since it's the one picked by
the spec image.
The CephVersion provided here needs to be the current running version
of Ceph for when it is later passed to OkToStop and checked with
IsAtLeast. If you are upgrading from a pre 14.2.1 version to a
version 14.2.1 or newer, IsAtLeast will incorrectly return true and
then fail trying to run mon ok-to-stop on a mon pod running a pre 14.2.1 version.

When a cluster is updated with a different image version, this triggers
a serialized restart of all the pods. Prior to this commit, no safety
check were performed and rook was hoping for the best outcome.
Now before doing restarting a daemon we check it can be restarted. Once
it's restarted we also check we can pursue with the rest of the
platform. For instance, with monitors we check that they are in quorum,
for OSD we check that PGs are clean and for MDS we make sure they are
all active.

Example of failure scenarios:
- requested PVC 500M = 500,000,000 bytes
- PV is created as:
(500M / 2**20)Mi = "476"Mi
But 476Mi = 476 * 2**20 = 499122176 < 500M
From the k8s documentation:
Claims will remain unbound indefinitely if a matching volume does not
exist. Claims will be bound as matching volumes become available. For
example, a cluster provisioned with many 50Gi PVs would not match a
PVC requesting 100Gi. The PVC can be bound when a 100Gi PV is added
to the cluster.
which is inline with the behavior observed in which a 500M PVC is never
bound. However, the documentation also states:
If a PV was dynamically provisioned for a new PVC, the loop will
always bind that PV to the PVC. Otherwise, the user will always get
at least what they asked for
which suggests that an _explicit_ binding can be created, and perhaps
something has changed with respect to this binding that has caused the
failures in newer versions of k8s.

This commit does:
* remove dead code SetCrushTunables()
* stop creating initial crushmap
There is no need to create an initial crushmap, since Ceph natively does
that for us.
We don't delete the existing configmap containing the initial crush map
of already deployed cluster, perhaps people are using for whatever
reason. It does not harm to keep it around.

This requirement is long gone and was reported in 2017. Clients should
have been updated by then, so there is no reason to set the CRUSH
tunable to such an old client. Actually, we should let Ceph run its own
tunable. They can always be changed later. Also, this was really
restrictive and applied on every orchestration and thus would override
any other config done by an administrator. Even worse, this will trigger
data movement back and forth...

If setting the fsgroup recursively on a shared filesystem mount is
not desirable, the fsgroup capability on the flex driver
should first be disabled in the operator env vars. Now the driver
will apply the fsgroup only at the top level instead of

Before performing the copy, the OSD init container now checks
destination path exists. If the destination exists, it skips the copy.
The OSD pods copy the rook and tini binaries into a shared volume using
an init container. In restarting pods, this copy could fail with 'text
file busy'(ETXTBUSY), because the destination file in the shared volume
could be under execution. The restarting pods will enter a
'Init:CrashLoopBackOff' state after this, leaving the ceph cluster
degraded. Skipping the copy will allow the init containers to complete
successfully, allowing the pod to restart.
Fixes#2674.

This commits fixes the upgrade for cluster running on 0.9.x and thus
have monitors listening on 6790.
The only downside is that the new messengers 2 protocol can not be
enabled because Ceph expects monitors to listen on 6789.
In order to enable messengers 2 your monitors will have to failover so
they can pick up both 6789 and 3300 ports, then and only then messenger
2 can be enabled.

We must expose the ceph version to the osd pod so that we can generate

We now run all the daemon with a new option from Nautilus 14.2.1 which
allows us to tell to a daemon to not log on file. However, we can decide
to activate logging by editing the configuration flag 'log_to_file' via
the centralized config store like this for a particular daemon:
ceph config set mon.a log_to_file true
This is useful when a daemon keeps crashing and we want to collect log
files on the system.
