Fix type validation warning for storage policy rings

Since 63688a14e5 was merged, this module
support configuring storage policies.

When multiple storage policies are used, we need to create multiple
object rings like object.ring.gz, object-1.ring.gz. However the current
regexp to validate the ring name does not consider this format and
shows the type validation warning when creating a non-default policy
rings.

This change updates the regexp used in validation to accept that
object-<number> format as well.
