> 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.
