The plugin provides some convenience for end users
when they deploy Openstack using OSH charts.
There are two plugin subcommands:
- get-values-overrides - generates values
overrides file names from a set of given feature gates.
If these files not found then it can try to
download them via HTTP.
- wait-for-pods - checks if all the containers of all running pods
are ready and if all jobs are successfully completed.
