Dimitris Athanasiou 12fd8e04e5 [ML] Allow marking a model snapshot with retain (elastic/x-pack-elasticsearch#880)
This change adds a retain field to model snapshots.
A user can set retain to true/false via the update model snapshot API.
Model snapshots with retain set to true will not be deleted by
the daily maintenance service regardless of whether they expired.

This allows users to keep always keep certain snapshots around for
potentially reverting to in the future.
