FeatureRequest: Create dedicated configuration directory

[scoopex]

If the scs-health-monitor is executed in a Docker container, it would be useful if all configuration files could be stored in a dedicated directory (clouds.yaml, env.yaml and ~/.kube/config). This would reduce the number of mounts and also make it much easier to run scs-health-monitor in a non-root container.

My suggestion would be that this is controlled via an environment variable SCS_HEALTH_MONITOR_CONFIG_DIR (i.e. <BASEDIR>/config).

The Openstack searchpath should be controllable via OpenStackConfig(config_files=[config_dir]), in the kubernetes client with the KUBE_CONFIG variable, and env.yaml seems to be a custom config for the tool.
