Support OIDC authentication with JWT token

[wboudiche]

Summary

• Actually LinShare mobile application supprts OIDC authentication with opaque token only, we suppose to add the OIDC with jwt token too.

• TODO: {link}
  The backend is ready so to detecte authentication mode, mobile application should send some headers in the call for jwt endpoint

For OIDC with JWT : X-LinShare-Auth-Provider = Oidc-Jwt

For OIDC with JWT : X-LinShare-Auth-Provider = Oidc-Opaque

And for both of them : X-Linshare-Id-Token = id token

For old release users for backend they should continue OIDC with opaque token by default and the backend configuration should be kept without modification
