virt.util_test: Add a new class for guest suspend test

This 'GuestSuspend' class contains some steps needed by
guest suspend test, it provides 2 methods:
 * guest_suspend_mem()
 * guest_suspend_disk()
They will run a 'standard' suspend testing.

If you want to custom suspend testing, you can just inherit
from this class and implement your own steps.

This class also provides 3 hook points:
 * action_before_suspend()
 * action_during_suspend()
 * action_after_suspend()
You can insert your own test steps in these test points.
