This implementation increases parallel write capabilities of the eventstore.
Please have a look at the technical advisories: [05](https://zitadel.com/docs/support/advisory/a10005) and [06](https://zitadel.com/docs/support/advisory/a10006).
The implementation of eventstore.push is rewritten and stored events are migrated to a new table `eventstore.events2`.
If you are using cockroach: make sure that the database user of ZITADEL has `VIEWACTIVITY` grant. This is used to query events.
This PR adds support for OAuth2 token revocation of V2 tokens.
Unlike with V1 tokens, it's now possible to revoke a token not only from the authorized client / client which the token was issued to, but rather from all trusted clients (audience)
This PR changes the information stored on the SessionLinkedEvent and (OIDC Session) AddedEvent from OIDC AMR strings to domain.UserAuthMethodTypes, so no information is lost in the process (e.g. authentication with an IDP)
This PR starts the OIDC implementation for the API V2 including the Implicit and Code Flow.
