#191

Description of changes:

Adds a new transition condition - min_rollover_age

This lets you transition to a new state based on when the index was rolled over instead of the index creation date to help with keeping data around for a specific amount of time.

As an index can be rolled over multiple times using different aliases (which is uncommon, i.e. I haven't actually seen that use case yet, so if you have this use case please comment on the PR) we will use the oldest rollover date that is available, i.e. the first one that happened. In the future if it seems like users want to specify which alias to use for this calculation we can introduce an index level setting to allow specifying the exact alias to use. I didn't include it for now in this PR as it seems like an unknown use case and we're starting to have a lot of settings introduced so want to limit them.

If the index evaluates this condition and the index was never rolled over, we will fail as this transition condition is only meant to be used after a rollover action has occured.
