Add a new package for parsing and interacting with ceph version
information. Previously ceph versions were limited to the release name,
and this patch supports ceph versions parts X.Y.Z for more fine grained
behavior.
The main structure introduced here in CephVersion which contains the
version parts. This will be used in the next patch to replace the Name
string component of the cluster CRD spec which was populated at runtime.

If someone sets limits to pod, we want to ensure the possible
experience, so we want to make sure that people do not configure
inapropriate values for certain daemons.
We decide to fail if the memory.limit is too low.

If the spec of the OSD daemon contains resource limits, especially
memory.limit we will use that value for setting the osd memory target
value so the bluestore OSD knows the amount of memory available for its
cache.

If the spec of the MDS daemon contains resource limits, especially
memory.limit we will use that value for setting the mds cache memory
limit value so the MDS knows the amount of memory available.

We now expose resource as environment variable in the pod.
They will be used by Ceph to report as a daemon metadata.

Only the args necessary have traditionally been passed to the mon package.
This has led to many properties in the mon struct, whereas we will
now simply pass the cluster crd spec to simplify.

The orchestrations need to be triggered on any update to the crd.
Users today restart the operator for various scenarios when the
operator could take care of it automatically. If unsupported options
are updated, they should just be ignored.
There are two goroutines that are working with the mons.
The first is an orchestration that is triggered by the operator
at startup, or when the cluster crd is updated. The second
is the health check that triggers periodically by default every
45 seconds. These goroutines must not try to make updates at the
same time. A mutex is added so one will block if the other is
still active. The mutex is only active for the duration of working
with mons, and not an entire orchestration of mgr, osd, etc

In the form of mon, mgr, mds, and rgw, convert the rbd-mirror to be
configured completely from the operator. This is a straightforward
conversion with one functional addition: the rbd-mirror daemon stores
*no* data and has no default data dir, so the concept of a `Dataless`
daemon is here introduced.

From ceph mimic (13.x) onwards, `mds deactivate` command is
deprecated. To scale down the number of active MDSes of a filesystem,
it's sufficient to set the desired number of active MDSes using
'max_mds' setting, and is no longer required to individually
deactivate the unwanted MDSes.
Resolves: #2725
