[HBase] Improves speed of unit tests on real HBase backend

Currently, unittests at real HBase are not usually used.
Jenkins jobs and a predominant amount of developers use
HBase mock. One of the reasons for this is that unittests at real
HBase are too slow. It's due to processing of "disable_table"
and "delete_table" commands. In HBase these command take up
to 1-2 seconds. Now we create all table-set for each test that's
why at real HBase unit tests may be executed several hours.
So, at real HBase backend unit tests may be executed several hours.

My CR speeds up this case. To solve this problem it was decided
to keep all test data in one table. To provide a distinguishability
of data from different tests unique row-prefix is used for each one.

Creating and deleting required table are implements at
setup-test-env.sh.
Separating data is implemented with mock.patchs which transforms row
value in happybase.Table methods.
