CLIP-1878: Update KinD scripts and config to be able to run DC functional tests

[bianchi2]

There's a handful of smallish changes to existing KinD scripts and configuration files to make them more flexible. Changes include:

• bump KinD and K8S version, make it possible to pass overrides or use default versions
• deploy an insecure container registry and map its NodePort on host port 5001 (not used at the moment but we may have scenarios where we need to build a local image and push it to the container registry)
• update Postgres deployment function, use the latest Helm chart version, optionally init database if the path to init file is passed
• make deploy script runnable on local Mac, use tmp locations for config files (to run sed against), avoid cd to directories, modify sed command when on Mac
• introduce MICS_OVERRIDES env var in which you can pass whatever --set you need
• group --set overrides to avoid duplication of --set
• optionally create hostPath PV and PVC (nfs server can't run on arm64 machines, so instead of nfs PV a hostPath PV is used)
• create backdoor NodePort services for the deployed DC app (with sts replica name as label selector and predefined NodePort which is mapped to a host port - 81 and 82)
• add additional env vars and sys props to common config to make deployed products ready for functional testing (disable welcome screen, enable insecure login etc)
• add comments to common config and deploy script to explain why we need extra values and what functions are doing

Where is this HOSTPATH_PV set? Do we set it when we want to run the test in our local arm64 machine?

[bianchi2]

Yes, that;s when we want to use it.

Where is this label being set?

[bianchi2]

That's leftovers from a lot of local debugging. Removed.
