PLAT-1573

This file serves as a location to store variables common to the services in Docker Devstack. It currently contains the variables for the LMS root URLs and OAuth/OpenID Connect configuration.

PLAT-1573

All services should use common_vars, so there is no need for an override.

- This removes the duplication across the various IDA configurations
- Updated Dockerfile for Docker-based devstack

LEARNER-817

We're stopping rabbit, but it's part of the configuration the service,
so I didn't use manage:.  We may need to re-discuss the tags (mongo_3_0
works similarly when stopping mongo to manage config).

Files for building a docker container for rabbitmq

Enforce correct rabbit version installed

Flag rabbit upgrading

Adds the CHECK_RABBIT_VERSION flag (true by default). If true and the
rabbitmq version found differs from the version specified in
RABBITMQ_VERSION, the role fails. If false in the same scenario, the
role continues but does not install rabbitmq (because it's already
installed).

This enables us to continue using this role without forcing us to
upgrade rabbitmq.

latest rabbit.

This Dockerfile is based on the official image (rather than built from scratch by us) and includes the elasticsearch-head plugin.

This playbook will install carbon-cache and graphite-api to provide a
minimalistic starting point for metrics collection.

It currently installs all components from their upstream source (albeit
with defaults that point to tags, and not master/development branches).
It uses systemd, and so is tailored specifically to Ubuntu 16.04.

It currently does not support any of the advanced configuration such as
multiple carbon-cache process + carbon-relay.  It is also lacking many
variables to fully tweak the various configuration files, although
there's support for fully configuring the storage schemas.

There is a small "master" playbook -- edx-monitoring -- for running the
role, and in the future, supporting the culmination of other playbooks
to build out an all-in-one monitoring server: Graphite, Grafana, etc.

Prompted because the awscli on go-agents needs to be above 1.10.47 to be
able to take advantage of IAM roles for tasks automatically.

ECOM-7207

- Added file to allow bower to install as root
- Added xvfb, firefox, and gettext packages for testing and local development

We originally made these changes when trying to debug the connection
between the go-agent and go-server.  Having them here makes it harder to
upgrade go-agent versions since they are regularly making improvements
to the upstream dockerfiles.
