a35a835e9c cephfs: fix logic to call ceph fs resize
clusterAdditionalInfo map is holding a localClusterState
for checking ceph cluster supports resize and subvolumegroup
is created or not, currently we are checking if the key is present
in a map and localClusterStatelocalClusterState.resizeSupported
is set to false to call ceph fs subvolume resize to check command is
supported or not, if a structure is  initialized all its members
are set to default value. so we will never going to check the
ceph fs subvolume  resize command is supported in backend or not, we are
always using ceph fs subvolume create to resize subvolume. in some
ceph version ceph fs subvolume create wont work to resize a subvolume.
This commit changes the resizeSupported from bool to *bool for
proper handling of this scenario.

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.

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.

31c7c95fdb cephfs: check error output contains Error: ENOENT
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.

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.

1e5370a1f3 cephfs: return volume not found error if volume doesnot exists
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.

```bash

Error ENOENT: subvolume 'csi-vol-a24a3d97-c7f4-11ea-8cfc-0242ac110012' does not exist
```
