Get a bearer token that may be passed to a third party to confirm ownership

of a matrix user id.

|
The format of the response could be made compatible with the format given
|
|
in http://openid.net/specs/openid-connect-core-1_0.html#TokenResponse
|
|
|
|
But instead of returning a signed "id_token" the response contains the
|
|
name of the issuing matrix homeserver. This means that for now the third
|
|
party will need to check the validity of the "id_token" against the
|

federation /openid/userinfo endpoint of the homeserver.
