UI should enable client certificate authentication

With client certificate authentication in place, the following would be the behavior seen by the user. Let’s say a user called “user_xyz” has been added to the Couchbase server.

1. First the user will have to generate a client certificate with “user_xyz” encoded in one of the subject.cn, san.uri, san.email or san.dns fields in the certificate.
2. The same certificate will then have to be added to the browser.
3. Then when the user points his/her browser to https://<IP>:18091 then the dashboard screen should be presented. There would be no prompt to accept username/password as the user has already been authenticated based on client certificate.

NOTE: If the client cert auth state is set to mandatory and if the browser doesn’t have the right client certificate configured then the UI will not be loaded.
