 Description   

Customer reported an error in create table with DDLProc connection lost, but DDLProc wasnt crashing, but the Ip address for DDLProc was pointing to UM2. But UM1 was the master and DMLProc was pointing to UM1.

So need to add in the oam code at startup a validation to check these ip addresses and get them insync, if they are out of sync..

how to test.

1. Do any type of system install and get the system to ACTIVE state.
2. from pm1, edit Columnstore.xml and change DDLProc or DMLProc Ip address
3. shutdown or stopsystem
4. startsystem
5. check Columnstore.xml and make sure DDL/DMLProc match and that are the same
as the PrimaryUMModuleName for multi-um node system or pm1 for single server

Fix is in branch MCOL-1509 - Issue is I cant get the Columnstore.xml to update correctly with DDLProc Ip address. Testcase is to shutdownsystem, edit IP of DDLProc on UM1 to UM1, then startsystem. It will not show an update

tried these with no avail:

1. sleep after the config write
2. make config and deleteinstance before current create
3. create new thread to make the config updates

no luck, updates made by setUMProcIPs functions just aren't getting maintained.

OAM is being deprecated and replaced by an enhanced API and the MaxScale orchestration project.
