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
dynamic topology to be configured. The location will now be ignored
if specified in the cluster CR.

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 osd-prepare jobs should not inherit osd resources since this might

A new CRD property `PreservePoolsOnDelete` has been added to Filesystem(fs) and
Object Store(os) resources in order to increase protection against data loss.
If it is set to `true`, associated pools won't be deleted when the main
resource(fs/os) is deleted. Creating again the deleted fs/os with the same name
will reuse the preserved pools.

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".

Starting with Nautilus 14.2.1 the dashboard SSL port is readed from <<mgr/dashboard/ssl_server_port>> ceph setting.
Previous versions use the port specified in <<mgr/dashboard/server_port>>
Addressed @travisn suggestion about use of <ssl> attribute in conditional.
This suggestion drove me to change the type of the SSl attribute (from *bool to bool) in the DashboardSpec Struct.
This makes code more clean/safe and make sure that the SSL atribute has always a meaningful value.
Now if you want to run the <secure dashboard> you need to set explicitly SSL to true, as is demonstrated in unit tests.

After further consideration and working with the feature for a few
weeks, the `configOverride` functionality seems to be more complexity
than is worth it for the expected benefit. Users still have the most
preferred option of setting configs in Ceph's config database using
`ceph cofig set` or the dashboard, and the override ConfigMap still
exists for fallback scenarios. The config database can still be used
by Rook for setting necessary configs, but the user has no way of
telling Rook to do so.

Allow users to specify overrides in the CephCluster CRD. The override
ConfigMap still exists for emergency situations and is mounted into

Rook Ceph no longer uses a config file for managing daemons with the

We need to ignore some monitor specs for the external cluster use case
otherwise the cluster will never start.
For an external cluster, the mon count and other values don't make sense

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

ganesha crd are created, the operator will simply print an error
to the log.

With the 1.1 release we should not be creating bluestore OSDs
with rook's legacy partitioning scheme. All new bluestore OSDs
should be created with ceph-volume. Therefore, the miminum

This commit also adds consistent version checking between
the Add and Update methods for the operator handling the
CR events.
