http: add client certificate user auth middleware

This populates the authenticated user from the client certificate
common name.

Also added tests for the existing client certificate functionality.

 You can either use an htpasswd file which can take lots of users, or
 set a single username and password with the ` + "`--{{ .Prefix }}user` and `--{{ .Prefix }}pass`" + ` flags.
 
+If no static users are configured by either of the above methods, and client
+certificates are required by the ` + "`--client-ca`" + ` flag passed to the server, the
+client certificate common name will be considered as the username.
+
 Use ` + "`--{{ .Prefix }}htpasswd /path/to/htpasswd`" + ` to provide an htpasswd file.  This is
 in standard apache format and supports MD5, SHA1 and BCrypt for basic
 authentication.  Bcrypt is recommended.
