When the cluster is external we want to expose manager service port
along with the endpoints.
This allows us to connect but Rook will keep on using 9283 as a facing
port for Prometheus and more.

Before cleaning up the cluster, we wait for all the daemon pods to be cleaned up. This fails when
a daemon is in pending state and has no NodeName. This PR ignores daemon pods that are not scheduled on any node.

We can now prioritize orchestrations on certain event. Today only two
events will cancel on-going orchestrations (if any):
* request for cluster deletion
* request for cluster upgrade
If one of the two are caught by the watcher we will cancel the on-going
orchestration.
For that we implemented a simple approach based on check points, where
we will check for a cancellation request in certain part of the
orchestration. Mainly before each mons/mgr/osds orchestration loops.
This solution is not perfect, but we are waiting for the
controller-runtime to release its 0.7 version which will embed context
support. With that we will be able to cancel reconciles more precisely
and rapidly.

Rook's crashcollector pod posts entries to the ceph cluster when a crash occurs.
Over time the number cluster may hold crash entries needlessly.
To clean up old crash entries, this PR adds a field to the ceph cluster CR for the user to specify the number of days a crash entry should be kept for.
Providing a value for the field keepXDays creates a cronjob that runs every day at midnight, calling "ceph crash prune <keepXDays>".

This will allow all the OSDs in the currently drained failure domain to be removed while blocking the deletion of OSDs in other failure domains.

with the network partitions or some other reason for one of the failure

The CRUSH map does not allow duplicate values (nor keys) for the
labels. That means that if the currently hardcoded label value
`default` occurs anywhere else in the tree (for example, because
some of the topology labels provided by the cloud provider use it),
the cluster cannot sucessfully spawn.
By giving the user control over the label value used for the root
CRUSH map label, it is possible to adapt the cluster to this
situation.
To be able to actually use the `default` value, the root=default
node which is created by default by ceph itself has to be removed;
since that node is accompanied by a replicated crush rule, we have
to remove that rule, too.
The integration tests are modified to sometimes use the custom
crushRoot (based on an arbitrary criterium) to get coverage across
the various suites. Separate tests could be added, but were not
deemed necessary at this point.

The ceph mons should never be started with an even number in quorum.
The desired state should always be an odd number of mons to ensure
a healthy majority quorum. The operator now rejects a request for
an even number of mons.
If there are not a sufficient number of nodes for mons to be on a
unique host, the operator also returns an early error instead of
getting stuck waiting for a pending mon. This is not foolproof since
there might be fewer available nodes for the mons, but at least it
is a quick check for the common case.

During the initialization encrypted OSD initialization sequence, we check
for the presence of the encrypted container. If it exists we don't try
to open it again since this will result in an error.
However, there is another case we need to handle, when the underlying
device is gone. For instance, if the pod/PV couple was drained and move
back, living the orphan dm. Once the pod comes back, the dm is still
present and perfectly matches. Unfortunately, the underlying disk is
different and thus the dm must be removed and the disk re-opened.
