BUG#16321920 : CREATE A SEPARATE INNODB_ZIP TEST SUITE
Fix :
-------
Created separate suites called innodb_zip ans i_innodb_zip that contain all compression tests.
Running the new suites with following compression-related parameters :
* innodb_compression_level = {1/9}
* innodb_log_compressed_pages = {ON/OFF}
