Take 2: Refactor hoodie-common and create right abstractions for Hoodie Storage V2.0

- Refactored timelines to be a single timeline for all active events and one for archived events. CommitTimeline and other timelines can be inferred by applying a filter on the activeTimelime
- Introduced HoodieInstant to abstract different types of action, commit time and if isInFlight
- Implemented other review comments
