Evaluate RefMarker logic to more accurate

[aslakknutsen]

What can be improved

Currently the Modifiers will mark the changed resources with a hash value to know if we're about to apply the same logic or not.

In all cases this is based on the Hash of the Ref from the Session object. However, modifiers like DestinationRule rely on more information, e.g. the version label from the target Deployment, that won't be reflected in the marker.

Why

Evaluate if each marker should capture the more fine grained and correct information about it's inputs to more precisely detect a change.
