Add the ClusterConnection to the volumeOptions type, so that future use
of go-ceph can connect to the Ceph cluster.
Once a volumeOptions object is not needed anymore, it needs to get
destroyed to free associated resources like the ClusterConnection.

When passing

in the StorageClass, the mount options passed on the ceph-fuse
commandline result in "-o nonempty ,debug". The additional space before
the ",debug" causes the mount command to fail.

It doesnot make sense to allow the creation of empty
volumes with readonly access, this commit allows the
creation of volume which is having readonly capabilities
only if the content source is set for the volume.

as the stderr will be the first string. its good

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.

The sentinel error code had additional fields in the errors, that are
used nowhere. This leads to unneccesarily complicated code. This
change replaces the sentinel errors in utils with standard errors
created with errors.New() and adds a simple JoinErrors() function to
be able to combine sentinel errors from different code tiers.

In Go 1.13, the fmt.Errorf function supports a new %w verb.
When this verb is present, the error returned by fmt.Errorf
will have an Unwrap method returning the argument of %w,
which must be an error. In all other ways, %w is identical to %v.

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.
