    Separate per-service host configuration tasks

    Currently there are a few services that perform host configuration
    tasks. This is done in config.yml. This means that these changes are
    performed during 'kolla-ansible genconfig', when we might expect not to
    be making any changes to the remote system.

    This change separates out these host configuration tasks into a
    config-host.yml file, which is included directly from deploy.yml.

    One change in behaviour is that this prevents these tasks from running
    during genconfig.

    This commit also includes a follow up to the original commit,
    I79fcbf1efb02b7187406d3c3fccea6f200bcea69: Perform host configuration
    during upgrade

    To maintain previous behaviour, and ensure we catch any host
    configuration changes, we should perform host configuration during
    upgrade.
