Title: clone indexes only when required

Rather than attempting to clone indexes every time we move data to a
partition, we will clone indexes only on creation of a partition
(following the first move of data to that partition).

This makes pg_rollingwindows less self-healing but avoids taking the
really obnoxious AccessExclusiveLock.
