Adds new helper chart

[mxmxchere]

The chart can be used to transform a clouds.yaml in its unmodified form as retrieved from openstacks horizon ui into:

• a namespace with the same name as the openstack project
• a secret in that namespace with the contents of the clouds.yaml
• a secret containing a secret that contains the cloud.conf with credentials from the clouds.yaml in the format that is expected by OCCM
• a clusterresourceset to automatically transfer the OCCM secret to any correctly labeled workload cluster

Currently this only works with clouds.yaml with username and passwort. Application credential clouds.yaml may be added in the future

[mxmxchere]

I'll add the possibility to use a clouds.yaml with applications credentials

So using a clouds.yaml with application credentials should work now too.
