Use Case

Using a Spring distributed cache to prevent watchdogs working on the same ADVISED cm handles during model sync, since we don't have an in-between state from ADVISED to READY.

Eg:

Watchdog A wakes up, works on Cm-Handle-1 which has state of ADVISED and stores this in memory

Watchdog B wakes up, attempts to work on Cm-Handle-1, which still has a state of ADVISED, but is being worked on by Watchdog A, so this then moves on to Cm-Handle-2
