Clarify debug message about initgroups and subdomains

The initgroups request is not handled by the IPA provider for
subdomain users on purpose because the group membership information is
not available on the IPA server but will be directly written to the
cache when the PAC of the user is processed. The old generic debug
message "Invalid sub-domain request type" might be misleading.

This patch adds a specific message for the initgroups case "Initgroups
requests are not handled by the IPA provider but are resolved by the
responder directly from the cache." and increase the debug level so
that typically this message is not shown anymore because it is expected
behaviour.
