    Gather script for containers

    Currently our gather playbook assumes all configuration files will be in
    /etc. This assumption isn't true with container deployments. Currently
    the configuration files are located in
    /var/lib/config-data/<service>/etc/<service>/.

    The Gather script needs to support both container and non-container
    deployments. This patchset updates the config parser python script
    to check if a service is in the running containers list and then
    determine it's appropriate path, grab all of multiple config files
    in that path, then parse and drop them off for ansible to use.

    This method automagically supports all possible mixes of containerized
    uncontainerized services and will always grab the correct config even
    if that changes build to build or run to run.

    It's also easily extensible for many possible config locations or
    different container types by adding another condition or additional
    search paths.
