Releasing Consensus for node 11.2

This is just a list so that I can keep track of the branches I have pending before releasing ouroboros-consensus for node 11.2.

_cardano-config and cardano-keys_
- Updating the bounds on cardano-keys, requires a release/revision: https://github.com/IntersectMBO/cardano-keys/pull/8
- Blocked on Ledger doing their release so that cardano-keys have no SRPs
- ~Fix the experimental genesis handling in cardano-config:~ https://github.com/IntersectMBO/cardano-config/pull/19
- ~Updating the bounds on cardano-config:~ https://github.com/IntersectMBO/cardano-config/pull/20
- Some changes that @johnalotoski identified, and then a 2.0 version bump: https://github.com/IntersectMBO/cardano-config/pull/22
- Use cardano-config and cardano-keys in consensus: https://github.com/IntersectMBO/ouroboros-consensus/pull/2259
- Approved but needs to address some comments

_tracing_
- Move the tracing instances into Consensus: https://github.com/IntersectMBO/ouroboros-consensus/pull/2244
- WIP, almost done

_others_
- https://github.com/IntersectMBO/ouroboros-consensus/issues/2301

This is a release-tracking checklist rather than a self-contained code task. Start by reviewing the referenced cardano-keys, cardano-config, ouroboros-consensus pull requests, and issue #2301; no files or tests are named, and done means completing the pending release work for node 11.2.
