[Platform] Check if configmaps are encrypted

[haskojur]

Title: [Platform] SECURITY test: ensure_cm_encrypted

Is your workload test idea related to a problem? Please describe.

• In Kubernetes systems, there's a risk that data stored in configmaps in etcd may not be adequately encrypted, potentially being only encoded. If data are merely encoded, they can be easily decoded by unauthorized individuals, compromising sensitive information.

Describe the solution you'd like

• This new test case aims to verify whether data stored in secrets are properly encrypted in etcd key-value store, thereby ensuring enhanced security of the Kubernetes environment. This will also follow best practices for Kubernetes configmaps.
