BGP always asks zebra for a chunk of MPLS label even if it doesn't need it.
Fix this by correcting the rounding up "labels_needed" formula.

Debugs take up a significant amount of cpu time as well as
increased disk space for storage of results. Reduce test
over head by removing the debugs, Hopefully this helps
alleviate some of the overloading that we are seeing in
our CI systems.

BGP LU will use implicit-null in more situations now; adjust
the original LU topotest to align with that. Node R2 uses
imp-null now, while R1 continues to allocate labels.

This test checks the interactions between the BGP label requesting
code and the labelpool code to ensure the correct number of labels
and label chunks are requested and those labels are freed back into
the pool when the corresponding prefix is removed.
