* @brief Checks that after setting 'session_track_gtids', the new set value follows ProxySQL rules
* for this particular variable. This is:
* - backend connections are by default set to `mysql-default_session_track_gtids`.
* - if `mysql-default_session_track_gtids=OFF` (the default), `session_track_gtids` is not changed on backend.
* - if the client asks for `session_track_gtids=OFF`, proxysql ignores it (it just acknowledge it).
* - if the client asks for `session_track_gtids=OWN_GTID`, proxysql will apply it.
* - if the client asks for `session_track_gtids=ALL_GTIDS`, proxysql will switch to OWN_GTID and generate a warning.
* - if the backend doesn't support `session_track_gtids` (for example in MySQL 5.5 and MySQL 5.6), proxysql won't apply it. It knows checking server capabilities
*
* @param expVal The value to which 'session_track_gtids' have been set.
* @param sVal The ProxySQL session value for 'session_track_gtids'.
* @param mVal The MySQL session value for 'session_track_gtids'.
* @return True in case the check succeed, false otherwise.
