Add v2 saver struct format #400

Closed stephen-soltesz closed 1 year ago

stephen-soltesz commented 1 year ago

This change adds a new saver struct format that will a) allow us to migrate from v1 to v2 seamlessly, b) separates the JobMap type into the same two types used natively by the tracker.Tracker.

After this change, the Tracker will attempt to load from the v1 struct, but will write state in the v2 saver struct format. On restarts, the Tracker will attempt to load both, but will prefer the one with the later SaveTime, which should always be the v2 type until we remove the v1 logic entirely.

This change is part of https://github.com/m-lab/etl-gardener/issues/349
