> When testing the ultradns-ws provider, Netflix noticed that migrating territories from one directional group to another to results in a drop of traffic and slow recovery.  The root cause is how updates must occur considering territory overlaps are illegal.
> Ex. first remove argentina from group a.  next add argentina to group b.
> Advice is to wrap the two commands into a transaction, which may eliminate some traffic loss scenarios.
> Implementation:
> expose a TransactionApi and a corresponding scope to attribute the transaction to any write commands within it.
