engine: forbid single (vm mem) > (host mem)

Forbid running single vm with mem > host physical memory.
Yet we allow running few vms with total mem > host physical memory. (relying on balloning).
This might be unwise yet can occour after migration or/and host downsizing.
Whenever the: (vm mem) > (host mem) the host will start swaping and performance degrage.
If it possible to think of scenrios vm allocated large mem and not using it, and cannot downsize vm mem.

Fix swap and refactor reused messages.

If fail run vm due to insufficent mem. Report the available mem.
Added unit test to SlaValidatorTest
