Ticket 47382 - Add a warning message when a connection hits the max number of threads
Bug Description: Currently there is no way to tell when a connection is at max threads.
Fix Description: Update cn=monitor, "cn=snmp,cn=monitor", snmp, etc to report on
the number of current active threads that are in a max thread state.
Report the number of times any connection has hit max threads. For
cn=monitor, extend the "connection" attribute to include three more
1 = Connection max threads state: 1 is in max threads, 0 is not
2 = The number of times this thread has hit max threads
3 = The number of operations attempted that were blocked
by max threads.
connection: 66:20130724195333Z:1:1:-:cn=directory manager:0:1:3
