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.
