[SPARK-2087] [SQL] Multiple thriftserver sessions with single HiveContext instance
Still, we keep only a single HiveContext within ThriftServer, and we also create a object called `SQLSession` for isolating the different user states.
Developers can obtain/release a new user session via `openSession` and `closeSession`, and `SQLContext` and `HiveContext` will also provide a default session if no `openSession` called, for backward-compatibility.
Author: Cheng Hao <hao.cheng@intel.com>
Closes #4885 from chenghao-intel/multisessions_singlecontext and squashes the following commits:
