* Moving test() contents into doctests

Stanford-oriented Datadog updates

* Datadog explicitly sets hostname in style Stanford uses (relies on
  /etc/hostname being accurate, requires reboot)
* Enables nginx status check module integration for datadog
* Installs nginx access log processor that counts HTTP response codes
* Updates to lots of other places to make sure that their logs appear
  where we expect
* Has sample code showing how to emit events from log contents which make it
  into the Datadog event stream
* Separation of stage and prod datadog configurations

install edxapp code sandboxing

* Changed the way xqueue does basic auth configuration so that it would
  work with the old httplib on our prod ora instances.
* this breaks the .org release's method of doing basic auth, but that
  doesn't matter for Stanford because we do it differently

* xqueue user creation fails mysteriously sometimes. We don't actually
  care if the user creation works because most of the time, the user has
  already been created. So, ignore these errors.

The ORA machinery gets gummed up when it gets very large submissions and
throws a lot of 500s.
