Set different hostname label for upcoming nodes #3883

Function copying template node to use for upcoming nodes was
not chaning hostname label, meaning that features relying on
this label (ex. pod antiaffinity on hostname topology) would
treat all upcoming nodes as a single node.
This resulted in triggering too many scale-ups for pods
using such features. Analogous function in binpacking didn't
have the same bug (but it didn't set unique UID or pod names).
I extracted the functionality to a util function used in both
places to avoid the two functions getting out of sync again.

I suspect this may have also been the root cause for #3721.
