Set Agent version correctly #264

Closed backstreetkiwi closed 3 years ago

backstreetkiwi commented 3 years ago

A running Stackable agent registers a node at the K8s API. In its metadata, it sets its version to the version of the underlying krustlet. It would be more convenient for us to see the actual stackable-agent version there. Additionally, we should remove/overwrite the label type so that it does no longer hold the value krustlet which might lead to wrongly scheduled pods if Stackable coexists with other platforms that use the krustlet.
