k8s: Drop support for Casablanca

Casablanca release reached End of Life (EOL) stage on July 8th 2019 [1].

This patch also fixes comments for test fixtures.

This whole test subtree will be deleted upon migrating Aquasec
kube-bench [2] for CIS Benchmark [3] integrated by Orange [4] to ONAP
xtesting [5].
