chore: Switch liveness probe to tcp socket instead of httpGet

[sbernauer]

Description

In SUP-159 a customer wanted to enable security for the Namenode HTTP API.
This resulted in /dfshealth.html returning a 401 instead of a 200 - thus failing the liveness probe.

This PR allows customers to configOverride security for the HTTP APIs (hopefully until we support them natively)

We intentionally did not write a curl script that checks for 200 or 401 but just went with the TCP port.
