Sébastien Han bd58790c31 ceph: proxy ceph commands when multus is configured
When the CephCluster is configured with Multus and multiple networks are
used to deploy Ceph some commands are failing to be executed from the
Operator. These commands, in particular, `radosgw-admin` ones need access
to the "ceph public network" to talk to OSDs. Unfortunately, the
Rook-Ceph Operator does not have the network annotations and thus
doesn't have the networks available and cannot reach OSDs. So the commands end
up hanging and eventually time out.
Applying the annotations to the Operator pod is possible but will result
in restarting the operator too and this should be avoided at all costs.
Also, applying the annotations beforehand is not possible since the
Multus declaration is in the CephCluster specification. So we would have
no idea what to do.

So the current approach runs a new sidecar container in the mgr pod to
act as a proxy for "some" ceph commands, only the `radosgw-admin` ones
for multi-site setup. This is a small container with admin access
running idle waiting for commands to be executed. In a sense, it is
similar to the toolbox but we didn't want to clearly expose it, so
running as a sidecar is quite nice.

Proxying command is obviously not always recommended since we add an
extra hop in the network path. Now each request has to go from the
operator pod to the API server to the remote pod to Ceph. Previously,
the command only goes from the operator to Ceph.

It's worth noting that external mode is not impacted since no rgw pod
is configured. This scenario is flexible and allows us to scale
pretty well since any CephCluster with Multus will see its mgr sidecar
deployed and can then talk to Ceph. We are not limited.

ceph: block delete object store when buckets and/or users exist

Blaine Gardner 7f516b9e3d ceph: ignore atari partitions when scanning disks
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.

Blaine Gardner d78b2a41d6 ceph: work around radosgw-admin fifo file io error
Work around issue https://github.com/rook/rook/issues/7573
and make sure integration tests check for regressions.

Eventually we should use the RADOS Gateway admin REST API, but for now
we need to work around an issue where the built version of
'radosgw-admin' has incompatibilities with the RADOS Gateway version
running in the Ceph cluster.

Of note, Rook built on the Ceph Pacific image will not support
some 'radosgw-admin' commands to Ceph Nautilus (v14) or Octopus (v15)
clusters.

Further complicating matters, the flag used for the workaround changes
between Ceph v16.2.0 and v16.2.1 (both Pacific).

This bug needs to be treated a little differently than most of the ways
Rook handles different commands for different Ceph versions because this
is based on the Ceph version that is installed in the container with the
Rook operator primarily and not the version of Ceph running in the
cluster.

Sébastien Han 2d75135579 ceph: embed the buffer in the error
Somehow the combined output does not contain the stderr in the errorn
only in the buffer.
For example:

err = "error exit 1"
buf = "Error EBUSY: not enough monitors would be available () after stopping mons [a]"

So we now embed the buf in the error so that the caller does not need to
print the buffer as well as the error.
Also, the caller can more easily decide to ignore the error by
instropecting the string.

Sébastien Han c08c3ced05 ceph: add support for metadata PVC for OSD on PVC
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

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

1. We removed all the function/methods/tests that were used to

It also fixes various go-lint issues in the respectives files.

2. use c-v inventory to detect available devices:

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
