Adding test case test_client_side_quorum_with_fixed_validate_max_bricks

Description:

Test Script with Client Side Quorum with fixed should validate
maximum number of bricks to accept

 * set cluster quorum to fixed
 * set cluster.quorum-count to higher number which is greater than
   number of replicas in a sub-voulme
 * Above step should fail
