Add Master_gtid_wait_{count,time,timeouts} status

Browse Source 
MASTER_GTID_WAIT function needs some status to evaluate its use.

master_gtid_wait_count indicates how many times the function is called.
master_gtid_wait_time indicates how much time in microseconds occurred
waiting (or timing out)
master_gtid_timeouts indicates how many time times this function timed
out rather than all successful gtids events being available.
