With this change, the admin can specify a single mon and the operator
will add any other mons to both ClusterInfo and the configmap of mon
endpoints.
It will periodically check for changes too and update both ClusterInfo
and the configmap accordingly.

With the 1.1 release we should not be creating bluestore OSDs
with rook's legacy partitioning scheme. All new bluestore OSDs
should be created with ceph-volume. Therefore, the miminum
version allowed is a version of mimic supporting ceph-volume.
This commit also adds consistent version checking between
the Add and Update methods for the operator handling the
CR events.

- Added code to support StorageClassDeviceSet spec provided in the cluster-on-pvc.yaml
- The code reads the StorageClassDeviceSet spec and creates pvc based on the ‘count’ field for each device set.
- OSD prepare job is started for each PVC which activates the ceph-volume on each PVC
- Finally OSD is started on each of the PVC device.

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.

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.

cmd-reporter runs a command and puts the results of the command into a
ConfigMap defined by its `--config-map-name` commandline flag.
cmd-reporter is intended to be run as a Kubernetes job where an
operator needs to run a single command and get return information back
from the command which is more than just success/failure.
The ConfigMap returned includes `stdout`, `stderr`, and `retcode` data
from the command. The ConfigMap may be preexisting, in which case
cmd-reporter will overwrite the return information in the ConfigMap.
cmd-reporter labels the ConfigMap with `app=cmd-reporter`, and if the
ConfigMap already has an app label which is different, cmd-reporter
fails without modifying the ConfigMap so as not to overwrite another
application's data in the event of a ConfigMap name+namespace collision.

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...

the only exception to a naive device list comparison had been to ignore
drive UUID information which was unreliable when a device wasn't
formatted / partitioned. however various users have reported different
type of false positives that resulted in orchestration being run
continuously due to the wrong observation that devices were changing.
this patch fixes the cases we have observed and attempts to be slightly
more conservative in the calculation.
1. the devlinks is ignored. when a device is setup for lvm, for example,
the devlinks will be updated with different paths that point to the
device in addition to its standard paths addressable by pci address.
2. in the lvm case, the "model" field and "filesystem" field may also
change.
3. we ignore devices with devlinks that contain "usb" to avoid issues
when using usb drives.
4. be smart about detecting device availability. if a device transitions
from a non-empty (or has-partitions) state to an empty (or unpartitioned)
state then orchestration is triggered. this like observing that a device
is now available (e.g. in the allDevices case). however, when a device
transistions from empty to non-empty, then this is ignored as while it
is a change, it's generally a change associated with the new consumption
of the device.

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.
