Even if we can use raw mode, do NOT use raw mode on disks. Ceph bluestore disks can
sometimes appear as though they have "phantom" Atari (AHDI) partitions created on them
when they don't in reality. This is due to a series of bugs in the Linux kernel when it
is built with Atari support enabled. This behavior does not appear for raw mode OSDs on
partitions, and we need the raw mode to create partition-based OSDs. We cannot merely
skip creating OSDs on "phantom" partitions due to a bug in `ceph-volume raw inventory`
which reports only the phantom partitions (and malformed OSD info) when they exist and
ignores the original (correct) OSDs created on the raw disk.

Ceph bluestore raw disks can sometimes appear as though they have Atari
(AHDI) partitions on them. If a disk has Atari partitions, we just
ignore them as though they don't exist. This should be a safe assumption
since the hardware was last manufactured in 1992 and likely can't run
Kubernetes.
If we don't ignore the Atari partitions, Rook can create a new OSD on a
disk that is already running an OSD, corrupting the first and possibly
also the latest OSD. This can happen an arbitrary number of times per
disk.

this commit will enable one more linter ineffassign
in golangci-lint.
This linter throws an error when variable is assigned and never used.
`golangci-lint run --disable-all -E ineffassign` is used detects ineffassign
errors only.

The helpers for executing a process have long required an actionName
param which is not being used. Now we remove the old param
while also cleaning up various other usages of the exec
package.

Multiple things:
1. We removed all the function/methods/tests that were used to
create and manage rook legacy OSDS as well as bringing support to
Bluestore OSD only.
It also fixes various go-lint issues in the respectives files.
2. use c-v inventory to detect available devices:
Now we rely on the 'ceph-volume inventory' command to tell us if a
device is available or not.
3. implement raw mode for osd on pvc
When an OSD will be bootstrap on a PVC, the new c-v raw mode will be
used. It consists of putting block, db and wal under the same device.
Here LVM is out of the picture and the raw device is used as is. The
implementation is backward compatible so existing OSD on PVC will LVM
will continue to operate.

We now support partitions via 2 ways:
* if `useAllDevice: true`: partitions will be taken into account and
presented as OSD candidate
* if specified in the cluster CR: it'll picked up as well

Since https://github.com/rook/rook/pull/4219, lv devices are now
presented to ceph-volume when preparing the device.
So on this initial run, this won't fail because the dm hasn't been
created yet but if an orchestration is re-triggered, the prepare pod
ensures idempotency with the ceph-volume batch command.
Unfortunately, c-v seems to have a bug where it doesn't read the dm to
detect whether or not they are ceph members already.

When both PARTNAME and ID_PART_ENTRY_NAME are specified, rook takes
PARTNAME in account, overriding ID_PART_ENTRY_NAME. As PARTNAME is not
always updated by the kernel after sgdisk --change-name, it's better to
do the opposite. It also makes GetDevicePartitions coherent with
parsePartLabel (called by GetPartitionLabel).

- 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.

run "rook discover" on storage nodes and discover devices on each node. The discovered disks are saved in a per node configmap, local-device-nodename.
Device information consits of name and persistent names, uuid, partition, filesystem, rotational, readonly, size, etc.
