Some log messages indicate when the upgrade checks will be
performed. If the Ceph image hasn't changed, the upgrade checks
are skipped. The messages were confusing if running a Rook
upgrade.

A new controller to bootstrap ceph-crash pod on Ceph nodes running Ceph
pods only.
This implementation is unfortunately a mix of 'hacks' to make the daemon
working correclty. The ceph-crash script faced different issues:
* it's not a daemon
* it does not have any key in cephx
* it runs ceph commands under the hood which need an admin key and a
ceph.conf
On upstream Ceph, ceph-crash needs to grow better, once that happens we
will improve our implementation.
This also enhances osd provisionConfig struct with DataPathMap
Pod volumes and volume mount needs DataPathMap to perform the right
actions on log and crash dir. Exposing DataPathMap makes that possible.
Obviously, this is exposing ceph crash reports on the host as
well as pushing them into the mgr.
Basically, if a daemon fails, it'll put its core dump into
/var/lib/ceph/crash, bindmounting this dir on the host, ensures that the
crashes don't get lost when the pod dies.
Example:

The topology of the cluster should be based on the node labels rather
than a setting in the cluster CR. This allows a much richer and more

We removed the topologyAware CRD option since it was redundant with the
use of an OSD being backed by a PVC.
So now, if an OSD is backed by a PVC we assume the topology aware
decision and will discover zone and region labels on that host.

The node labels were already supported for zones and regions to add to
the CRUSH map. Now all layers of the CRUSH map will be supported
with the new labels such as topology.rook.io/rack.
The labels will be detected at the osd startup time
similar to the zone and region labels already being detected.

Even legacy osds were still running with this flag. In my previous patch
I was trying to minimize the impact of the change and was afraid the
config file was holding important information but that appears not to be
true.
The only option in the config could have the keyring path, but it's
passed in the CLI startup line.

OSD on PVC does not upgrade when the user upgrades the ceph version on cluster-on-pvc yaml.

- upgrade osd prepare and daemon pods on upgrade
- skip c-v prepare if filesystem is already present on the pvc device.
- skip lvm release in case of upgrade.

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.

Just as with the mon, mgr, mds, rgw, and rbd-mirror daemons, do not
generate a ceph.conf in an init container for directory-based OSDs.
Instead use the mon config database and the commandline to supply all
the needed arguments for running these OSDs.
Also generate a keyring secret to mount to OSD pods. Use this
secret for directory-based OSDs for now with the intention to
use this for other OSDs in the future.

This is just one small unit of work that still results in usable
dir-based OSDs. The goal is to build on this to run dir-based OSDs using
the new config patterns used by the other Ceph daemons. This also

OSD containers.

We don't need to force any Ceph config file for ceph-volume based OSDs
since the 'ceph-volume activate' command mount everything at start time
in the right place.
So now, OSD will keep running normally and they will also read back
normally the default location of the ceph configuration:
/etc/ceph/ceph.conf which will allow OSDs to read any configuration
overrides.
We cannot remove the generation of that file in /var/lib/rook/osd* since
we cannot tell at the stage that triggers the generation if we run
ceph-volume or not. So let's keep it around for some time.
If you are wondering how the OSD connects to the mons this is done via
the CEPH_ARGS env variable which was introduced in
https://github.com/rook/rook/pull/3894.

When running osds on pvc, the lvm is still holding the device when the cluster is deleted. As a result the PVs go into `failed` state
when the cluster is deleted. On deactivating the device, the 'failed' pvs get deleted as well. Solution involves:
- Running `lvchange -an <vg group name>` to deactivate the device.
- This command runs after 'osd prepare' completes.
- This command also runs after the 'osd daemon pod' is deleted or if the ceph-osd process terminates for some reasons.

The node selector for running OSDs on PVCs was using the node name
rather than the node's hostname. In clusters where the node name
is different from the hostname this would cause the osd daemons
to be in pending state indefinitely. Now the node selector will
use the hostname as expected.

On rare occasion, the ceph checks might not be 100% correct and the user
might decide to force an upgrade anyway.
Correctly, if we are in an upgrade, we perform `ok-to-stop` check for
each daemon, if one of them fails, we retry and eventually fail.
They are corner-cases where users would like to force the upgrade anyway.
Enhance the new CR property: "skipUpgradeChecks: true".

Several commands were not using the cli finalizer function which builds
up the right argument to run a ceph command. This was working on the
operator since it used to have an /etc/ceph/ceph.conf file so we could
ran the command without specifying the ceph conf and key paths.
However, we recently removed that and it silently broke this "already"
broken code :).
