This adds a check if the datastore and the namespace is valid when a
user attempts to add a new PBS datastore.
Since the namespace only can be checked after the datastore is
validated, the datastore will be checked as well, regardless that it
will be done later in the superclass anyway.
The functionallity to check namespaces is added with this commit. For
checking the datastore, existing code that has previously been
refactored will be reused
