In order to support --check we need to ensure that registered
vars exist before checking their stdout. Otherwise ansible
errors out.

Make it easier to use a local pypi mirror in the roles listed above

Always write the supervisor files and link them as necessary.

Drop the configs in the supervisor available directory. Instead of having a
seperate cfg dir for each service.

Seperate devstack logic from disabling supervisor tasks. Add the new flag so
devstack continues to not startup supervisor. Use new supervisor_available_dir
everywhere.

Remove mongo logic from abbey and remove stage_release. This should completely
remove our tie ins to mongo.

Also removing monitor repos script which depended on stage_release. We can add
in similar logic when we're ready to automate building the AMIs on rc branch
creation.

Updated requirements.

services if it changes
deploy tasks no longer stop the service and will notify the restart
if any task changes

`supervisorctl reload` not only reloads the configuration files, but
also restarts all services, which causes all services to be reloaded
several times, and causes errors when the playbook later attempts to
start the services after changes have been applied.

* Instead of using pypi.edx.org why not cache on localhost?
  Seems to work well and it does result in a speed improvement
  for when we need to download packages. This adds the devpi
  role as dependency for edxapp
* For edxapp we md5sum all fo the requirements files and only
  run the pip installs, bundle, npm tasks if any one of those
  files have changed (it treats them as a group)
* Adds convenience symlinks for pip

Source the `activate` file instead of attempting to execute it, which requires
execution rights.
