This patch adds support for new service level cql queries. The queries implemented are: CREATE SERVICE_LEVEL [IF NOT EXISTS] <service_level_name> ALTER SERVICE_LEVEL <service_level_name> WITH param = <something> DROP SERVICE_LEVEL [IF EXISTS] <service_level_name> ATTACH SERVICE_LEVEL <service_level_name> TO <role_name> DETACH SERVICE_LEVEL FROM <role_name> LIST SERVICE_LEVEL <service_level_name> LIST ALL SERVICE_LEVELS LIST ATTACHED SERVICE_LEVEL OF <role_name> LIST ALL ATTACHED SERVICE_LEVELS
