WiP: Add Malfeasance V2 Handler and Publisher

[fasmat]

Motivation

This adds the a malfeasance handler that will be used when ATX v2 goes live.

Description

This PR simplifies the existing malfeasance handler to only handle V1 proofs (which will eventually be retired in a future release) and adds a handler for V2 proofs.

Additionally publishers for V1 and V2 proofs have been added. Shifting the responsibility for publishing proofs from the components (activation, etc.) to a dedicated service. This also allows to simplify handling of proof publication since the components now don't need to keep track any more if they are in sync or not before publishing a proof (the publisher now keeps track of this instead).

The new DB table malfeasance requires foreign key constraints so these have now been enabled using PRAGMA foreign_keys = ON;. The new table will keep track of malicious identities and their proofs. The existing identities table will in future only be used to keep track of which identities belong to which marriage set and the proofs in them will be dropped with the V1 publisher / handler of malfeasance proofs. (Proofs will be migrated to V2)

Test Plan

• Existing tests were updated
• new tests were added for the new components

TODO

• Explain motivation or link existing issue(s)
• Test changes and document test plan
• Update documentation as needed
• Update changelog as needed
