Feature/jrbl/prod cleanups

* Rename auth_config and env_config to be specific to LMS and CMS
* Minor CMS configuration cleanups elsewhere

* Move sudo:True out of each task and into the playbook, since it's a
  playbook-level variable
* Removal of a couple debian package installs from common that are also
  being installed in the role where they're needed
* Re-correction of /etc/git-identity permissions
* Other cleanups (whitespace issues, etc.)

* Removes HTTP basic auth

* Enable npm role
* Minor edits to debian dependency list
* Change treatment of a few files and directories

* Needs more work, but seems to have many of the basics.

  out and logs back in.

where it can take a {{ service_variant }} param

We need to use the git protocol to access read-only git repos.  It's a
quirk that when these are referenced from pip files, they need to go
over a source control protocol.  I wish it could go over http/s or ssh,
but it can't, so port 9418 it is.

I had to open inbound and outbound 9418 to get this working, don't know
why.  Leaving both open for now, will debug later so we can close down.
