Start backup with strict security mode - Run LibVMI with event monitoring

[SunnyRaj]

How do we make sure, the first iteration of backup runs on a event handling mode? Do we have a flag that says remus to run backup on a restrictive mode?

Also, when we start backup, it would continue from where we left off. Remus is probably not going to run at this point. So does it make sense to integrate LibVMI event handling inside remus? On the other hand, is there a case where we need LibVMI event stuff to run for a single checkpoint? In that case, we might need to integrate or else not.

@nks5295 @twood02 What are your thoughts on this?
