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.
Added a generic token hook that is called for all grant types and includes `payload` with a single allowed value - `assertion` to cover the `jwt-bearer` grant type customization.
The existing `refresh token hook` is left unchanged and is considered to be deprecated in favor of the new hook logic. The `refresh token hook` will at some point be removed.
