Following the Ceph OSD rework, my test environment regularly failed to
start OSDs, as they would start before the postStart lifecyle hook which
was chown'ing the log and data directories could finish. Pods failed to
start for an arbitrarily long time before starting successfully. This
was a manifestation of a race condition identified in Ceph monitors in
https://github.com/rook/rook/pull/3594#discussion_r312279176
Create a Ceph operator-level method to create an init container that
will chown the necessary directories for all Ceph daemons (any daemon
which runs as the ceph:ceph user-and-group). Also add this container to
expectations for Ceph pod templates in unit tests.

Allow users to specify overrides in the CephCluster CRD. The override
ConfigMap still exists for emergency situations and is mounted into
daemon pods directly instead of being merged into a Rook-created config
file.
Rook Ceph no longer uses a config file for managing daemons with the
exception of the OSDs which still generate a config in an init
container.

When configuring an external cluster the orchestration of discover and all the ceph
daemons will be skipped. The operator will still watch for the creation of
crds for this namespace. When a filesystem, object, object user, or
ganesha crd are created, the operator will simply print an error
to the log.

Before each pod starts, the daemon changes the ownership of
/var/log/ceph which is bindmounted on a hostPath.
On OpenShift envionments, the container must be privileged in order to
successfully change the owernship.

At the beginning of every container startup we now change the ownership
of every known ceph directories to ceph:ceph.
This will allow daemons to start properly as well as allowing daemon to
writes their logs on files.
This is needed because ceph daemon now run as 'ceph' instead of 'root'

This commit does multiple things:
* remove support for AllNodes where we would deploy one rgw per node on
all the nodes.
* a transition path is implemented in the code so that if someone has an
existing deployment, daemonsets will be removed and replaced by an
deployments.
* when using "instances", each rgw deployed has its own key which makes
Ceph reporting the exact number of rgw running, see:

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.

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.

Upgrading a Ceph objectstore was failing the upgrade test because the
existing method for handling the case where update errors occurred
because labels and label selectors have changed was not robust enough.
Make this more robust by attempting delete-and-create if a normal update
does not work on an rgw deployment.

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.

Configure the Ceph rgw daemon completely from the operator a la the
recent changes to the Ceph mon, mgr, and mds operators.
Create the rgw deployment or daemonset first, and then create the
keyring secret for the object store with its owner reference as the
corresponding deployment or daemonset. When the replication controller
is deleted, the secret is also deleted.
The RGW's mime.types file is now stored in a configmap with a different
file created for each object store. This is primarily just a means to
get the mime.types file into the rgw pod, but the added benefit is that
the administrator can modify the configmap, which could reduce
susceptibility to file type execution vulnerabilities (worst case).
