Add interface to query current state to HAServiceProtocol

      Description

      Let's add an interface to HAServiceProtocol to query the current state of a NameNode for use by the the CLI (HAAdmin) and Web UI (HDFS-2677). This essentially makes the names "active" and "standby" from ACTIVE_STATE and STANDBY_STATE public interfaces, which IMO seems reasonable. Unlike the other APIs we should be able to use the interface even when HA is not enabled (as by default a non-HA NN is active).
