Support: urn:ietf:params:oauth:grant-type:jwt-bearer

I'm working on suporting URLs as client_id in Community Solid Server when used with client_credentials. I encountered a limitation related to multiple users using a client with the same client_id, since it is a URL. While in this case it relies on Soild-OIDC it could as well use OAuth Client ID Metadata Document.
I would like to prototype alternative flow using grant type defined in JSON Web Token (JWT) Profile for OAuth 2.0 Client Authentication and Authorization Grants which is curently unsupported by this library.
Would it be possible to add support for this grant?

All of what you're linking is implementable using the existing extensibility. Client ID metadata is easily done inside the Adapter. And the grant is basically just a framework that I cannot imagine an abstraction for other than the existing one.

Thank you! It can be done indeed.
I have a very rough PoC in this draft PR and over next weeks I should get it properly implemented.
