> The method {{Resource.Clone()}} shows up quite often in various heap profiles
> which were captured on busy clusters (see screenshot).
> One of the call sites of this method is {{Node.preAllocateCheck()}} which
> calls this method in the scheduling cycle very often:
> {noformat}
> // check if resources are available
> available := sn.GetAvailableResource()
> // returns true/false based on if the request fits in what we have
> calculated
> return available.FitInMaxUndef(res)
> {noformat}
> However, cloning is not necessary. We can pass "res" to the Node which
> returns a boolean whether the request can fit or not, therefore we avoid
> memory allocations.
