Rook uses global or node-local device class configuration if device-level
configurations doesn't exist. However, after introducing device-class
level resource configuration, rook set the default value of device class.
So global or node-level device class configuration has never been used
after that.

Rook supports raw mode OSD in host-based cluster. So we can also
support OSD on logical volume in this kind of cluster.
Logical volumes aren't picked by filters (i.e. `useAllDevices: true`
and `device{Path,}Filter` to avoid unwanted LV consumption on upgrade.

This is handling a tricky scenario where the OSD deployment is manually
removed and the OSD never reconvers. This is unlikely to happen, but
still OSD should be able to run after that action. Essentially after a
manual deletion, we need to run the prepare job again to re-hydrate the
OSD information so that the OSD deployment can be deployed.
On encryption, it is a little bit tricky since ceph-volume list again
the main block won't return anything, so we need to target the encrypted
block to list.
There is another case this PR does not handle, which is the removal of
the OSD deployment and then the node is restarted. This means that the
encrypted container is not opened anymore. However, opening it requires
more work like writing the key on the filesystem (if not coming from the
Kubernete secret, eg,. KMS vault) and then run luksOpen. This is an
extreme corner case probably not worth worrying about for now.

The previous exit 32 check for loop device is 5 years old. Also, if the
device cannot be read it will be skipped anyway so let's report the
error and not hide it.
Signed-off-by: Sébastien Han <seb@redhat.com>
Sometimes the error does not tell much, so as `exit status 1` and
printing the output along returning the error is useful.
For instance, I saw a job failing with no osd and the prepare job had
those lines:
```
exec: Running command: lsblk /dev/sdb1 --bytes --nodeps --pairs ....
inventory: skipping device "sdb1". exit status 1
```
We need to understand more about the lsblk issue.

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.

We now support the addition of the PVC that acts as a metadata device
for a given OSD.
For this, you need to create a new `volumeClaimTemplates`, its name must
be "metadata" otherwise, Rook won't pick it up.
A template will look like this:
```
volumeClaimTemplates:
- metadata:
name: data
spec:
resources:
requests:
storage: 10Gi
# IMPORTANT: Change the storage class depending on your environment (e.g. local-storage, gp2)
storageClassName: gp2
volumeMode: Block
accessModes:
- ReadWriteOnce
- metadata:
name: metadata
spec:
resources:
requests:
storage: 6Gi
# IMPORTANT: Change the storage class depending on your environment (e.g. local-storage, gp2)
storageClassName: gp2
volumeMode: Block
accessModes:
- ReadWriteOnce
```
We now map block and block.db directly inside the container instead of
running ceph-volume activate. This is much cleaner.

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.

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.

"OSD on PVC" doesn't work for PV backed by LV. Fixing this problem
by the following changes.
- Rook accepts LVM disk type.
- If a LV-backed device is passed, Rook/Ceph invokes
"ceph-volume lvm prepare" with "--data vg/lv"
instead of "--data /path/to/device".
- If a LV-backed device is passed, Rook/Ceph suppresses
activation/deactivation of VG that owns this LV.

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.
