DNS sites support - SRV DNS lookup plugin

https://fedorahosted.org/sssd/ticket/1032

This plugin mimics the current behaviour.

If discovery_domain is set it is the only domain that is tried.
If discovery_domain is not set, we try to autodetect domain first
and if that fails or SRV lookup on this domain fails, we fallback
to SSSD domain name.
