`cap` builtin function returns the capacity of a type. Its not
good practice to use this builtin function for other variable
names, removing it here

golang-ci suddenly complains about the following issue
internal/cephfs/util.go:41:1: directive `// nolint:unparam // todo:program values has to be revisited later` is unused for linter unparam (nolintlint)
// nolint:unparam // todo:program values has to be revisited later

Dropping the comment completely seems to fix it. Ideally
execCommandJSON() will get removed once the migration to go-ceph is
complete.

volJournal.Connect() got the error on err2 variable, however
the return was on variable err which hold the error return of
DecomposeCSIID() which is wrong. This cause the error return wrongly
parsed and pushed from the caller. From now on, we are reusing the
err variable to hold and revert the error of volJournal.Connect().

There is no need to pass all secrets on to newVolumeOptions(), it only
needs the credentials. As the caller of newVolumeOptions() already has
the credentials generated, just pass them along instead of the raw
secrets.

The go-ceph CephFS Admin API needs a rados.Conn to connect the Admin
interface to the Ceph cluster. As the rados.Conn is internal to the
ClusterConnection type, add GetFSAdmin() to create a new FSAdmin
instance for a specific connection.

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.
