Allow users to run the scouting app with HTTPS/LDAP

I find myself needing to experiment with getting the username from the
LDAP login that happens in our HTTPS version of the scouting app. This
patch exposes a new `//scouting:https` target to let me do just that.

This patch also updates the README to let other folks know how to run
it under HTTPS/LDAP.
