3     ** sp_monitor_crt_mon_config
4     **
5     **	Utility procedure to [re-]create control table, mon_config in tempdb.
6     **	Caller can optionally ask for table to be dropped and then recreate it.
7     **	If not, and if table already exists, we leave it alone. Else, create
8     **	a new one.
9     **
10    ** Parameters:
11    **	@do_drop	- Boolean; whether to drop table and then create it.
12    **	@callerID	- To trace who is calling us. (Debugging hook)
13    **
14    ** Returns:
15    **	@@error code from drop/create work, if any.
