Code Issues Proposed changes

Convert existing roles into galaxy roles

Browse Source 
This change implements the blueprint to convert all roles and plays into
a more generic setup, following upstream ansible best practices.

Items Changed:
* All tasks have tags.
* All roles use namespaced variables.
* All redundant tasks within a given play and role have been removed.
* All of the repetitive plays have been removed in-favor of a more
  simplistic approach. This change duplicates code within the roles but
  ensures that the roles only ever run within their own scope.
* All roles have been built using an ansible galaxy syntax.
* The `*requirement.txt` files have been reformatted follow upstream
  Openstack practices.
* Dynamically generated inventory is now more organized, this should assist
  anyone who may want or need to dive into the JSON blob that is created.
  In the inventory a properties field is used for items that customize containers
  within the inventory.
* The environment map has been modified to support additional host groups to
  enable the seperation of infrastructure pieces. While the old infra_hosts group
  will still work this change allows for groups to be divided up into seperate
  chunks; eg: deployment of a swift only stack.
* The LXC logic now exists within the plays.
* etc/openstack_deploy/user_variables.yml has all password/token
  variables extracted into the separate file
  etc/openstack_deploy/user_secrets.yml in order to allow seperate
  security settings on that file.

Items Excised:
* All of the roles have had the LXC logic removed from within them which
  should allow roles to be consumed outside of the `os-ansible-deployment`
  reference architecture.

Note:
* the directory rpc_deployment still exists and is presently pointed at plays
  containing a deprecation warning instructing the user to move to the standard
  playbooks directory.
* While all of the rackspace specific components and variables have been removed
  and or were refactored the repository still relies on an upstream mirror of
  Openstack built python files and container images. This upstream mirror is hosted
  at rackspace at "http://rpc-repo.rackspace.com" though this is
  not locked to and or tied to rackspace specific installations. This repository
  contains all of the needed code to create and/or clone your own mirror.

contributor guidelines
^^^^^^^^^^^^^^^^^^^^^^
Filing Bugs
-----------
Bugs should be filed on Launchpad, not GitHub: "https://bugs.launchpad.net/openstack-ansible"
When submitting a bug, or working on a bug, please ensure the following criteria are met:
* The description clearly states or describes the original problem or root cause of the problem.
* Include historical information on how the problem was identified.
* Any relevant logs are included.
* The provided information should be totally self-contained. External access to web services/sites should not be needed.
* Steps to reproduce the problem if possible.
Submitting Code
---------------
Changes to the project should be submitted for review via the Gerrit tool, following
the workflow documented at: "http://docs.openstack.org/infra/manual/developers.html#development-workflow"
Pull requests submitted through GitHub will be ignored and closed without regard.
Extra
-----
Tags:
If it's a bug that needs fixing in a branch in addition to Master, add a '\<release\>-backport-potential' tag (eg ``juno-backport-potential``). There are predefined tags that will autocomplete.
Status:
Please leave this alone, it should be New till someone triages the issue.
Importance:
Should only be touched if it is a Blocker/Gating issue. If it is, please set to High, and only use Critical if you have found a bug that can take down whole infrastructures.
Style guide
-----------
When creating tasks and other roles for use in Ansible please create then using the YAML dictionary format.
Example YAML dictionary format:
.. code-block:: yaml
- name: The name of the tasks
module_name:
thing1: "some-stuff"
thing2: "some-other-stuff"
tags:
- some-tag
- some-other-tag
Example **NOT** in YAML dictionary format:
.. code-block:: yaml
- name: The name of the tasks
module_name: thing1="some-stuff" thing2="some-other-stuff"
tags:
- some-tag
- some-other-tag
Usage of the ">" and "|" operators should be limited to Ansible conditionals and command modules such as the ansible ``shell`` module.
Issues
------
When submitting an issue, or working on an issue please ensure the following criteria are met:
* The description clearly states or describes the original problem or root cause of the problem.
* Include historical information on how the problem was identified.
* Any relevant logs are included.
* If the issue is a bug that needs fixing in a branch other than Master, add the ‘backport potential’ tag TO THE ISSUE (not the PR).
* The provided information should be totally self-contained. External access to web services/sites should not be needed.
* If the issue is needed for a hotfix release, add the 'expedite' label.
* Steps to reproduce the problem if possible.
