Add new action so it can use filtered data

Browse Source 
This commit adds evacuate_vm_action which is a wrapper for nova.evacuate
API call, but it checks the result of filtering from previous step, before
executing evacuation.

Also change a little bit workflow and filter action, so they suit new
approach
