We need to fix k8s deployment of kernelci-api / kernelci-pipeline as old script not up to date

Deploy scripts are outdated and many variables (for example kernelci-api secrets) are not properly deployed.
It is better to rewrite them entirely

Start by reviewing the deployment scripts responsible for kernelci-api and kernelci-pipeline, then identify which variables and secrets are currently handled incorrectly. Compare the scripts with the deployment requirements and consider the rewrite complete when both services and their secrets are deployed correctly; the issue names no specific files or tests.
