This adds some helper scripts for managing the edx server.

Supervisor could wait up to 5 days for workers to finish jobs. So
Upstart needs to wait that long for supervisor to finish.

In order to let supervisor run by the jenkins user. Don't use the word daemon in the process call.

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

devstack to not use pre_supervisor

typo error

Taking out edxapp_pypi_local_mirror, replacing with COMMON_PYPI_MIRROR_URL

Adding back - for white space

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
