DNS sites support - SRV lookup plugin interface

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

Introduces two new error codes:
- ERR_SRV_NOT_FOUND
- ERR_SRV_LOOKUP_ERROR

Since id_provider is authoritative in case of SRV plugin choise,
ability to override the selected pluging during runtime is not
desirable. We rely on the fact that id_provider is initialized
before all other providers, thus the plugin is set correctly.
