This reverts commit b7a564e929, reversing
changes made to 6996571b5c.
Reverting: Linking ceph noout to a node taint.
The taint is applied for reasons other than maintenance as well.
This also needs a way to respect user-set noout.
Need to revisit this with a better design.

This commits allows the upgrade from Mimic to Nautilus to work by:
* removing the v2 brackets on the operator ceph config file generation,
we stick with v1 and can revert this back once we deprecate mimic there
is no rush since mons keep on listening to v1.
* enable messengers 2 when the cluster runs on Nautilus

The CephCluster CR contains settings that are needed by other
CRs to configure the Ceph daemons. When the CephCluster CR
is updated, the updates will now be passed on to each of the
CR controllers to ensure the daemons are updated properly
without requiring an operator restart.
When calling the controllers from another controller,
we ensure that only a single goroutine is handling
CRs at any given time to prevent contention across
multiple CRs of the same type.

As per https://github.com/ceph/ceph/pull/26856 Ceph tunes the value of
osd-memory-target when running the OSD process so there is no need to
enforce it.
We also set a safety factor to that value which has been calculated by
the Ceph eng/perf team. Without this factor, the OSD will get OOM killed
since it is consuming memory for other purposes too.

Allow the user to set annotations in the CRDs of the following operators which will then be set on
the resulting Pods (Deployments, StatefulSets and so on).
Operators:
* Cassandra
* Ceph
* CockroachDB
* EdgeFS
* Minio
* NFS
The Annotations related structures have been added to the
rook.io/v1alpha2 pkg.

We must expose the ceph version to the osd pod so that we can generate
the proper ceph configuration file. If we don't do this all the version
check will assume they run the opposite of the desired version and the
formatting of the `ceph.conf` will be wrong.

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.

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.

When instanciating an osd, we now pass clusterInfo which basically
represents a collection of information about a particular Ceph cluster. Rook uses information
// about the cluster to configure daemons to connect to the desired cluster.
From clusterInfo, we use the CephVersion which helps us putting
conditions for our code execution.

Add a `rook-version` label to all controller resources used by Ceph:
deployments, daemonsets, and jobs. Labels are added to controller
resources only and not to the pod templates within because changing pod
templates causes updates due to the label change. The controller
resources themselves are not updated with the label addition and
therefore don't cause an unnecessary upgrade.

Make the Ceph operator more cautious about when it decides to remove
nodes from the Rook-Ceph cluster which are acting as osd hosts.
When `useAllNodes` is set to `true` we assume that the user wants to
have the most hands-off experience. Node removals are allowed when a
node is delted from Kubernetes and when a node has its taints/affinities
modified by the user (but not by automatic k8s modification as much as
possible).
When `useAllnodes` is set to `false` the only time a node is removed is
if it is removed from the Ceph cluster definition.

The CephCluster resource will now expose the health of the ceph cluster
so admins can query the status with k8s api or kubectl instead of
needing to run the rook toolbox. The operator will query the
ceph status periodically and update the status in the custom resource.

The Ceph mon flag `--public-bind-addr` does not keep the same port as
the previous daemon run when the port is left off the flag's value. A
port is undesired since that could interfere with Nautilus' msgr2
protocol, so instead configure the mon's services to forward the default
bind port on pods (6789) to the mon endpoint's port. The endpoint port
will be 6789 for new mons, but it may be 6790 for legacy clusters.

(cherry picked from commit 94bf2a6e14b88a8e965b4ad5ce1289b606e5c32d)
The desired number of mons could change depending on the number of nodes in a cluster.
For example, three mons would be the min number of mons in a production cluster with at
least three nodes. If there are five or more nodes, the number of mons could increase
to five in order to increase the failure tolerance to two nodes.
This is accomplished by a new setting in the cluster CRD preferredCount. If the number
of hosts exceeds preferredCount, more mons are added to quorum. If the number
of hosts drops below the preferred count, the operator would reduce the quorum size to
the smaller desired count.
