nlreturn linter requires a new line before return
and branch statements except when the return is alone
inside a statement group (such as an if statement) to
increase code clarity. This commit addresses such issues.

We have many declarations and invocations..etc
with long lines which are very difficult to follow while doing
code reading. This address the issues in 'internal/cephfs' package to
restrict the line length to 120 chars.

This can happen when the subvolume is in snapshot-retained state.
We should not return error for such case as it is a valid situation.

Fixes#1764
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.

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.

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.
