This patch improves Ory Hydra's ability to deal with refresh flows which, for example, concurrently refresh the same token. Furthermore, graceful token refresh has been improved to handle a variety of edge cases and scenarios.
Additionally, serializability errors in CockroachDB are now correctly retried.

Closes https://github.com/ory/hydra/pull/3895
This patch optimizes the performance of authorization code grant flows by minimizing the number of database queries. We acheive this by storing the flow in an AEAD-encoded cookie and AEAD-encoded request parameters for the authentication and consent screens.
BREAKING CHANGE:
* The client that is used as part of the authorization grant flow is stored in the AEAD-encoding. Therefore, running flows will not observe updates to the client after they were started.
* Because the login and consent challenge values now include the AEAD-encoded flow, their size increased to around 1kB for a flow without any metadata (and increases linearly with the amount of metadata). Please adjust your ingress / gateway accordingly.
