When using https display https://common_name:8080/ as one of the valid hostnames

This is a feature request, to display the valid SSL name (from the certificate) when starting up the server.

Steps to reproduce the issue, if applicable. Include the actual command and output and/or stack trace.

$ http-server -S

Starting up http-server, serving ./ through https
Available on:
  https://127.0.0.1:8080
  https://192.168.77.123:8080

What did you expect to happen?

$ http-server -S

Starting up http-server, serving ./ through https
Available on:
  https://127.0.0.1:8080
  https://192.168.77.123:8080
  https://the_name_in_cert.pem:8080

If the issue is a feature request, what is the motivation / use case for it?

To make it easier to:

1. You are using the correct SSL cert
2. Easier to click though to a URL that has the valid cert. Both 127.0.0.1 and 192.168.77.123 would display certificate errors.
