[ST] Enhance DrainCleanerST

[im-konge]

Type of change

• Enhancement

Description

This PR enhances the DrainCleanerST with following:

• moves the test from ACCEPTANCE to REGRESSION
• evicts just one Pod of kind Kafka or ZK
• lower the number of messages
• uses correct installation files folder (kubernetes/openshift) based on cluster type
• cleans the whole test a bit
• fixes NetworkPolicy for webhook in case of OCP

Additionally, it adds new method isOpenShiftLikeCluster() to KubeClusterResource, which is useful in case that we want to determine, if the cluster is "OpenShift-like" -> in our case OpenShift or MicroShift.

Checklist

• Make sure all tests pass
