Single process management operation timeouts

Portion of the parent task related to operation execution within a single process (i.e. not involving intra-process calls in a domain).

Potential points to apply the timeout:

ModelControllerImpl.acquireLock()

Questionable, as blocking here means waiting for another op, not a problem with the current op

ModelControllerImpl.awaitContainerMonitor() -> ContainerStateMonitor.await() -> StabilityMonitor.awaitStability()

This is the typical blocking point in a server op
– on way in, fail the op
– on way out (OperationContextImpl.releaseStepLocks()) log a WARN/ERROR

ModelControllerImpl.awaitContainerStateChangedReport()
– on the way in, before VERIFY

OperationContextImpl.waitForRemovals()
– on way in, before VERIFY
– on way out, in handleRollback
---- problem: this is called repeatedly
