RESP: Expose DP method getAccountDomain() to responders
Adds a tevent request that calls the getAccountDomain DP method.
This request will be used by responders to locate an object's domain.
At the moment, only looking up UIDs and GIDs is supported.
Internally, until we switch to the rdp_ interface everywhere, this
interface hooks into the sss_dp_issue_request(). When we switch to
the rdp_ interface, we'll be able to provide a nicer method parameters
as well.
