The OSD needs to shut down quickly during upgrade, or other scenarios
where the OSD is being restarted. To facilitate this fast shutdown,
rook will run kill -9 on the osd process. The Ceph OSD is designed
to be safe even when killed like this. This allows the
ECONNREFUSED to be returned sooner, which will redirect the OSD
traffic to other OSDs and cause less downtime.

When the OSD is running on a PVC, the LV needs to be released immediately
after the OSD process exits. The cleanup was being skipped when the OSD
process exited and returning an error rather than allowing the
LV cleanup to proceed.

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

PopulateDeviceInfo() in pkg/clusterd/disk.go returns nil as *sys.LocalDisk
if an error has occurred. This causes a nil pointer exception at
getAvailableDevices() in pkg/daemon/ceph/osd/daemon.go. At least the returned
value should be checked at the caller.
I added an explicit error to the return value of PopulateDeviceInfo(). This
naturally revokes an error check at the caller.
I modified PopulateDeviceUdevInfo() in the same file too.

Previously, "run dir" was used to place a number of file and config on
dataDirHostPath. Now, since a lot of configs and options have moved
either on the OSD's startup CLI line or remove with bluestore we don't
need to change the default.
Also, it was confusing for user and difficult to find the socket.
The is is not breaking any config in dataDirHostPath since all the
elements (keyrings) are hardcoded in the config file.

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.

OSD pods when running on PVC fail randomly due to some race condition:
- OSD daemon pod was activating the volume group using vgchange -an without any volume group name.
- This caused the pods to fail randomly when number of OSDs is more, say greater than 10.
- This fix adds Volume group name while activating/deactivating volume groups to fix this

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
exception of the OSDs which still generate a config in an init

- Added code to support StorageClassDeviceSet spec provided in the cluster-on-pvc.yaml
- The code reads the StorageClassDeviceSet spec and creates pvc based on the ‘count’ field for each device set.
- OSD prepare job is started for each PVC which activates the ceph-volume on each PVC
- Finally OSD is started on each of the PVC device.

Before performing the copy, the OSD init container now checks
destination path exists. If the destination exists, it skips the copy.
The OSD pods copy the rook and tini binaries into a shared volume using
an init container. In restarting pods, this copy could fail with 'text
file busy'(ETXTBUSY), because the destination file in the shared volume
could be under execution. The restarting pods will enter a
'Init:CrashLoopBackOff' state after this, leaving the ceph cluster
degraded. Skipping the copy will allow the init containers to complete
successfully, allowing the pod to restart.
Fixes#2674.

Rook's behavior should not be to create a default OSD in dataDirHostPath
when no devices are present on a node. Any preexisting fallback osd
should be kept as long as no dirs or disks have been specified to keep
the legacy behavior for those clusters running with these osds in place.
The legacy deletion behavior is also kept, removing the osd as soon as
any dir or device is specified other than the dataDirHostPath dir.
