chore(v2): Split powertools idempotency module (without redis impl)

[scottgerring]

Issue #, if available:
#1504

Description of changes:

Takes @eldimi 's changes from #1513 for the module split only. I've rebased the commits from 0ec7f4a0d7424c24cb402f23f6896111f257ac44 to 6da6aaf6b558edb56b18dd71e2f0ed1a7a8d8d13 inclusive onto v2. We will merge this and take the redis implementation in later.

It's not clear to me if v2 is broken or if there's something subtle in the changeset here that breaks the validation module. The build errors seem unrelated to the changeset.
