287b2ba7bd MCOL-3247 CS uses thread plugin variables since MCOL-1101 that aren't 
good for transmiting cal_connection_info to handler::close_connection().
This variables are then erased in THD::cleanup() and the cal_connection_info
is replaced in handler::delete_table with an empty structure.
handler::close_connection() recevies cal_connection_info with empty cal_conn_hndl.
This patch uses THD::ha_data that is supposed to be used in such occasions.

06696f596a MCOL-1101 Add plugin variables to replace the legacy system vars. 
Legacy system vars with names infinidb_* was preserved for
    backward compatibility and they will be used if
    columnstore_use_legacy_vars variable is set.

    Remove unused structure and plugin variable.

3bf269b3f7 MCOL-1519 GROUP BY handler now uses an appropriate SELECT_LEX structure. 
Before that handler used an outter query SELECT_LEX that could give
	incorrect information for subquery.
