rpc/auth: allow SSL identity to be used for authorization

Access to a volume is now controlled by the following options, based on
whether SSL is enabled or not.

 * server.ssl-allow: get identity from certificate, no password needed

 * auth.allow: get identity and matching password from command line

It is not possible to allow both simultaneously, since the connection
itself is either using SSL or it isn't.
