core: added utility methods for huge pages

It will mostly be used by the scheduler to know where to schedule this VM to.

Added two methods:
- isBackedByHudepages: returns true if the VM has a custom property defined and
  it is a valid integer
- getHugePages: returns a map "huge page size" -> "required amount". It returns
  it in this format and not as a HugePage object to easy the processing by the
  scheduler.

Implemented in a separate utility class because it can not be part of the
VMBase due to it's dependency on CustomPropertiesUtil and it's transitive
dependencies.
