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.

This prepares resizeVolume() so that the volumeOptions.conn can be used
for connecting with go-ceph and use the connection cache.

The credentials are not used anymore, the volume object is already
connected to the cluster when createVolume() is called.

we should not return the CLI errors in GRPC errors
we need to return proper readable error messages
to the user for better understanding and better
debugging.

execCommandErr returns both error and stderror
message. checking strings.HasPrefix is not helpful
as the stderr will be the first string. its good
to do string comparison and find out that error
is volume not found error.

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.

All calls to util.ExecCommand() now pass the context.Context. In some
cases this is not possible or needed, and util.ExecCommand() will not
log the command.
This should make debugging easier when command executions fail.

In some ceph version if the subvolume is not present, the
ceph returns doesnot exists and in some version not found
error message. This commit fixes issue for both error
checks.
By only checking Error ENOENT: for doesnot exist seems good.
even if some error message changes in ceph ceph-csi wont get
any issue.

With the current code base, the subvolumegroup will

subvolumegroup creation is not allowed again.
Added support multiple subvolumegroups creation by
validating one subvolumegroup creation per cluster.

The name of the CephFS SubvolumeGroup for the CSI volumes was hardcoded to "csi". To make permission management in multi tenancy environments easier, this commit makes it possible to configure the CSI SubvolumeGroup.
related to #798 and #931
The internal/ directory in Go has a special meaning, and indicates that
those packages are not meant for external consumption. Ceph-CSI does
provide public APIs for other projects to consume. There is no plan to
keep the API of the internally used packages stable.
