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.

Use dictionary for service group mappings Change the 'nova_service_names' from a list to a dictionary mapping of services, groups that install those services. This brings the method into line with that used in the os_neutron role in order to implement a more standardised method. The init tasks have been updated to run once and loop through this mapping rather than being included multiple times and re-run against each host. This may potentially reduce role run times. Currently the reload of upstart/systemd scripts may not happen if only one script changes as the task uses a loop with only one result register. This patch implements handlers to reload upstart/systemd scripts to ensure that this happens when any one of the scripts change. The handler to reload the services now only tries to restart the service if the host is in the group for the service according to the service group mapping. This allows us to ensure that handler failures are no longer ignored and that no execution time is wasted trying to restart services which do not exist on the host. Finally: - Common variables shared by each service's template files have been updated to use the service namespaced variables. - Unused handlers have been removed. - Unused variables have been removed.
