Change subject: engine: Added infrastructure for providing a canDoactions in 
case of locks
......................................................................


Patch Set 1:

The reason for using pair is the following:
for example we have same family lock for two operations (LockingGroup.Disk) 
copy disk and create template from it both acquired read lock, but we want 
provide different error message. For example, user will try to acquire a write 
lock (Remove Disk or Move Disk operation) and it should get: Can not do ..., 
because of disk is copying and used for template creation
