HTH: Enable zero-config with a specified admin and username.  Enables full install on zero-config.

This allows admin username/password to be set in local_settings.py, as well as a default facility, so that we can ship "zero-config" installs to partners:

Via website:
* They tell us admin/password name, desired facility name
* We set local_settings.py, download the package zip
* They unzip, run the install, and start the server

Or, via USB/SD:
* We have a standard KA Lite package (install not run)
* We drop a local_settings file (and json for zone, if we want)
* When the server is started, everything installs and is ready tog o.
