Extend Docker authorization with TLS user information

Browse source 
Currently Docker authorization framework does not use any user
information, which already available in the Docker context for TLS
connection.
The purpose of this CR is to complete the existing authz work by adding
the basic client certificate details (SUBJECT_NAME) and authentication
method (TLS) to the authz request.

We think this should be the default behavior when no extended
authorization module is specified (currently WIP under #20883).
