> Should be done after IGNITE-6022. We should allow optional streaming mode for JDBC driver.
In this mode only INSERTs without SELECT should be possible. All other DML operations should
throw an exception. 
> Design considerations:
> 1) Add command {{SET STREAMING=1|ON|0|OFF}} which will enable or disable streaming for
connection.
> 2) Add command {{STREAMER FLUSH}} which will force data flush.
> 3) Only INSERT without SELECT works, all other DML statements should throw an exception
> 4) It should be possible to stream into several tables simultaneously (i.e. several streamers
could be opened)
> 5) Any DDL statement should force flush of all currently opened streamers.
