Resolve SIDs in Web UI

Introduce new command, 'trust-resolve', to aid resolving SIDs to names
in the Web UI.

The command uses new SSSD interface, nss_idmap, to resolve actual SIDs.
SSSD caches resolved data so that future requests to resolve same SIDs
are returned from a memory cache.

Web UI code is using Dojo/Deferred to deliver result of SID resolution
out of band. Once resolved names are available, they replace SID values.

Since Web UI only shows ~20 records per page, up to 20 SIDs are resolved
at the same time. They all sent within the single request to the server.
