Activate Local Snapshots

[hmoog]

Description

This PR replaces the refactored classes and activates local snapshots. It is not the last PR, yet since we want to integrate the missing repair routine and the requester thread but local snapshots should be fully functional already.

Good

Just a few changes

[GalRogozinski]

All the Impls should be removed.
This is because: The D in Solid states that the code should depend on abstractions, not concretions.

The Impl is sort of a feature that help you enforce D. Everytime you see it you know D breaks. Besides it is ugly so it incentivizes you to use the interface :-)

This is so we can use all the implementation specific methods like "init", "start" and so on without having to typecast them to their explicit type again. I could have the field be generic and then do

((MilestoneSolidifierImpl) milestoneSolidifier).init(...) but that kind of makes it more complicated imho

[GalRogozinski]

hmm
Once we will do proper DI we will fix it

For now it is fine
