They fail with

  Waiting for system status:               An error occurred building
  AMI for loadtest edx edxapp.  The Exception was IndexError('list index
  out of range',)

I'm guessing that it is this list index lookup, but seems likely.  Hard
to test as it requires AWS slowness.

configure worker settings via worker_django_settings_module

OPS-1593 As an operator, I want sudo_user converted to become user in roles and plays, for compatibility with Ansible 2.x

This breaks when you add a new person, but a previous person removed a key.

Other than removing that user you have no recourse to add the new user.

We need a better warning mechanism for this, but we need to stop
failing.

This happens before common unfortunately so we can't rely on much
to exist.  Even pip is not installed till common.

This change is needed because we recently moved from the get_url module to the uri module.

adding httplib2 as a requirement

Handle the non-build-from-scratch case

app has replaced the word cluster with app in the create ami CD playbook

We only run the previous stanza if git and pip are missing.
So if you have an existing 14.04 image and cut a new one, you'll
still run into problems where ansible dies missing httplib2 and we
never install it without a scratch build.
