Patch Set 1:

[added more maintainers to hear more opinions]
i have a concern with this patch,
the new method invokes the commands to execute in parallel,
which may conflict with execution logic of the commands,
for example running multiple vms sort them and execute in that order (making 
sure HA and high prio. are tried to run first..)

there are  different implementations for multipleActionRunner,
each with implementation to runCommands(),
but the new method is not using it, making these implementations not to be 
executed, and specific logic is not used.

although i think its nice to have this ability (running in parallel), it should 
not hidden,
we need to know when to use it (for example PersistentSetupNetworks are run in 
parallel)
we maybe can change this method name to declare explicitly its running in 
parallel (maybe invokeSyncCommandsInParallel), and go over all implementations 
and think of implementation for this case.
