I'm afraid it doesn't. We didn't make sufficient progress with the V3 API (which is what incorporates domains) to include that with the Folsom release. We expect this to be available with the grizzly release.

If by "cluster" you mean multiple instances to handle requests, then absolutely - yes. For this particular response, I'll assume you're using a SQL backend for Keystone. Generally you maintain a single "database" - wether that's an HA cluster or a single instance, and any number of Keystone service instances can point to and use that.
