66aa595e77 cephfs: do not export internal CloneStatus type
getCloneInfo() does not need to return a full CloneStatus struct that
only has one member. Instead, it can just return the value of the single
member, so the JSON type/struct does not need to be exposed.

This makes the API for getCloneInfo() a little simpler, so it can be
replaced by a go-ceph implementation later on.

As the function does not return any of the unused attributes anymore, it
is renamed to getCloneStatu() as well.

68bd44beba rbd: add new controller to regenerate omap data
In the case of Disaster Recovery failover, the
user expected to create the static PVC's. We have
planned not to go with the PVC name and namespace
for many reasons (as in kubernetes it's planned to
support PVC transfer to a new namespace with a
different name and with new features coming in
like data populator etc). For now, we are
planning to go with static PVC's to support
async mirroring.

During Async mirroring only the RBD images are
mirrored to the secondary site, and when the
user creates the static PVC's on the failover
we need to regenerate the omap data. The
volumeHandler in PV spec is an encoded string
which contains clusterID and poolID and image UUID,
The clusterID and poolID won't remain same on both
the clusters, for that cephcsi need to generate the
new volume handler and its to create a mapping
between new volume handler and old volume handler
with that whenever cephcsi gets csi requests it
check if the mapping exists it will pull the new
volume handler and continues other operations.

The new controller watches for the PVs created,
It checks if the omap exists if it doesn't it
will regenerate the entire omap data.

8d3a44d0c4 rbd: add minsnapshotsonimage flag
An rbd image can have a maximum number of
snapshots defined by maxsnapshotsonimage
On the limit is reached the cephcsi will
start flattening the older snapshots and
returns the ABORT error message, The Request
comes after this as to wait till all the
images are flattened (this will increase the
PVC creation time.  Instead of waiting till
the maximum snapshots on an RBD image, we can
have a soft limit, once the limit reached
cephcsi will start flattening the task to
break the chain. With this PVC  creation time
will only be affected when the hard limit
(minsnapshotsonimage) reached.

565038fdfd cephfs: ignore quota when SubVolumeInfo() returns Infinite
There is a type-check on BytesQuota after calling SubVolumeInfo() to see
if the value is supported. In case no quota is configured, the value
Infinite is returned. This can not be converted to an int64, so the
original code returned an error.

It seems that attaching/mounting sometimes fails with the following
error:

    FailedMount: MountVolume.MountDevice failed for volume "pvc-0e8fdd18-873b-4420-bd27-fa6c02a49496" : rpc error: code = Internal desc = subvolume csi-vol-0d68d71a-1f5f-11eb-96d2-0242ac110012 has unsupported quota: infinite

By ignoring the quota of Infinite, and not setting a quota in the
Subvolume object, this problem should not happen again.

8a41cd03a5 journal: fix reading omaps from objects with large key counts
The implementation of getOMapValues assumed that the number of key-value
pairs assigned to the object would be close to the number of keys
being requested. When the number of keys on the object exceeded the
"listExcess" value the function would fail to read additional keys
even if they existed in the omap.
This change sets a large fixed "chunk size" value and keeps reading
key-value pairs as long as the callback gets called and increments
the numKeys counter.

36469b87e2 util: make ExecComand return stdout and stderr as string
Most consumers of util.ExecCommand() need to convert the returned []byte
format of stdout and/or stderr to string. By having util.ExecCommand()
return strings instead, the code gets a little simpler.

A few commands return JSON that needs to be parsed. These commands will
be replaced by go-ceph implementations later on. For now, convert the
strings back to []byte when needed.

47d5b60af8 rbd: disable reflink while creating XFS filesystems
Current versions of the mkfs.xfs binary enable reflink support by
default. This causes problems on systems where the kernel does not
support this feature. When the kernel the feature does not support, but
the filesystem has it enabled, the following error is logged in `dmesg`:

    XFS: Superblock has unknown read-only compatible features (0x4) enabled

Introduce a check to see if mkfs.xfs supports the `-m reflink=` option.
In case it does, pass `-m reflink=0` while creating the filesystem.

The check is executed once during the first XFS filesystem creation. The
result of the check is cached until the nodeserver restarts.
