a40cb58118 Wait for container ssh after apparmor profile update
This patch adds a wait for the container's sshd to be available
after the container's apparmor profile is updated. When the
profile is updated the container is restarted, so this wait is
essential to the success of the playbook's completion.

It also includes 3 retries which has been found to improve the
rate of success.

Due to an upstream change in behaviour with netaddr 0.7.16 we
need to pin the package to a lower version until Neutron is
adjusted and we bump the Neutron SHA.

ffb701f8a3 Removed default lxc profile on container create
Having the lxc container create role drop the lxc-openstack apparmor
profile on all containers anytime its executed leads to the possibility
of the lxc container create task overwriting the running profile on a given
container. If this happens its likley to cause service interruption until the
correct profile is loaded for all containers its effected by the action.

To fix this issue the default "lxc-openstack" profile has been removed from the
lxc contianer create task and added to all plays that are known to be executed
within an lxc container. This will ensure that the profile is untouched on
subsequent runs of the lxc-container-create.yml play.

e148635e78 Add role system-crontab-coordination
Currently every host, both containers and bare metal, has a crontab
configured with the same values for minute, hour, day of week etc. This
means that there is the potential for a service interruption if, for
example, a cron job were to cause a service to restart.

This commit adds a new role which attempts to adjust the times defined
in the entries in the default /etc/crontab to reduce the overlap
between hosts.

8e6dbd01c9 Convert existing roles into galaxy roles
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.

81c4ab04f7 Remove and/or rename Rackspace related bits
This patch removes and/or renames anything that is Rackspace specific
from the playbooks, roles and variables.

It also removes items which appear to be orphaned/unused and flattens
the playbooks into a single directory in order to better match ansible
best practise (and remove some horrible fiddles we were doing).

The following have been removed due to RAX/RPC naming or RAX/RPC
specific usage:
 - playbooks/monitoring
 - playbooks/rax*
 - playbooks/rpc*
 - roles/maas*
 - roles/rax*
 - roles/rpc*
 - scripts/f5-*
 - scripts/maas*
 - scripts/rpc*
 - scripts/*lab*
 - vars/repo_packages/rackspace*
 - vars/repo_packages/rax*
 - vars/repo_packages/rpc*
 - vars/repo_packages/holland.yml

The following have been removed as they are unused:
 - playbooks/setup/host-network-setup.yml
 - roles/openssl_pem_request
 - roles/host_interfaces
 - scripts/elsa*
 - ssh/
 - vars/repo_packages/turbolift.yml

The following directories have been renamed:
 - etc/rpc_deploy > etc/openstack_deploy
 - rpc_deployment > playbooks

The playbooks have all been moved into a single directory:
 - rpc_deployment/playbooks/infrastructure/* > playbooks/
 - rpc_deployment/playbooks/openstack/* > playbooks/
 - rpc_deployment/playbooks/setup/* > playbooks/

The following files have been renamed:
 - lxc-rpc > lxc-openstack
 - lxc-rpc.conf > lxc-openstack.conf
 - rpc_environment > openstack_environment
 - rpc_release > openstack_release (etc and pip)
 - rpc_tempest_gate.sh > openstack_tempest_gate.sh
 - rpc_user_config > openstack_user_config

The following variables have been renamed:
 - rpc_release > openstack_release
 - rpc_repo_url > openstack_repo_url

The following variables have been introduced:
 - openstack_code_name: The code name of the upstream OpenStack release
   (eg: Juno)

Notable variable/template value changes:
 - rabbit_cluster_name: rpc > openstack
 - wsrep_cluster_name: rpc_galera_cluster > openstack_galera_cluster
