amazon ami 1.1.3

problem is because we removed the mysql rep setup after the startsystem, which now causes this issue. need to investigate further

work around fix..

after module has been added, enabled started. run the following command to get the MariaDB/MySQL Replication setup on it.

mcsadmin enableMySQLReplication

fixed.. code changes

1. ProcMgr addModule at the end:
start mysqld on new modules
call setupmysqlrep()
stop mysqld on new modules
2. Changed in ProcMgr setupmysqlrep to allow sending to a newly addmodule that was disabled
3. ProcMon removed a check in the master rep setup where it checks if module is active, not
needed
4. postConfigure - in helper.ccp, removed a comment out error on mysqlrep when a module is
disabled.

To test...

Addmodule 0n a um or local query pm.
Enablemodule / startsystem

Check mysql rep slave setup on new module

Reproduced the issue in 1.1.3-1

Build verified: 1.1.4-1 ami (ami-66036f1e, US-west)

Verified that replication slave started after adding um2 and enabling the it.
