Client - Self Signed JWT Auth

A client, which is secured with self-signed JWT can be used to connect to a secured service.
The client is enriched with the Authorization: Bearer <token> header by passing the http:JwtIssuerConfig to the auth configuration of the client. A self-signed JWT is issued before the request is sent.

For more information on the underlying module, see the OAuth2 module.
