Add swift-sync role and environment

Add the swift-remote host group and environment file.

Add an os_swift_sync role which will sync the swift ring and ssh keys
for swift hosts (remote and not-remote). Which has the following:
 * Moves the key and ring tasks out of os_swift role to os_swift_sync.
 * This adds the use of the "-r" flag that was added to the
   swift_rings.py and swift_rings_check.py.
 * Adds a ring.builder vs contents file consistency check.
 * Adjusts the rsync process to use the built-in synchronize module
 * Ensure services have started post ring/ssh key sync.

Adds environment file and sample configuration file for swift-remote
hosts (conf.d).

Move appropriate default vars to the os_swift_sync role, and remove them
from the os_swift role.

Rename the "os-swift-install.yml" playbook to "os-swift-setup.yml" as
this handles only the setup, and add a playbook to for both
os-swift-sync.yml and an overarching playbook (os-swift-install.yml)
that will call both the os-swift-sync.yml and os-swift-setup.yml
playbooks. This means the funcitonality of "os-swift-install.yml"
remains unchanged.

Adjust the run-playbooks.sh so that it calls the new overarching swift
playbook.

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.
