CHANGE MASTER Inconsistent Behavior for Repeat Arguments

This runs successfully without any warnings and results in 0, 1, 2, 3.

CHANGE MASTER TO do_domain_ids=(0), do_domain_ids=(2, 3, 3, 1, 3, 2);

#=> Replicate_Do_Domain_Ids = '

This warns "less than 1 millisecond, reset to 0, meaning disabled", despite ending up with 60.

CHANGE MASTER TO master_heartbeat_period=0.00001, master_heartbeat_period=60

This (and only master_use_gtid) aborts with an ER_DUP_ARGUMENT error.

CHANGE MASTER TO master_use_gtid= NO, master_use_gtid= SLAVE_POS;

For consistency's sake, if not UX's (reduce confusions and mistakes), all CHANGE MASTER options should err (or at least warn) ER_DUP_ARGUMENT.
