Use queue for get_subdomains

It does not make much sense to run multiple get_subdomains request in
parallel because all requests will load the same information from the
server. The IPA and AD provider already implement a short timeout to
avoid the multiple requests are running to fast after each other. But if
the timeout is over chances are that if two or more request come in fast
the first request cannot update the timeout and request will run in
parallel. To avoid this the requests are queued and send one after the
other to the provider.
