OPNET-629: Use HAProxy monitor endpoint instead of API

[cybertron]

This is the runtimecfg change corresponding to
openshift/machine-config-operator#4767
which switches the monitor call to the HAProxy endpoing rather than
call through to the API.

I also included a commit to bump the Dockerfile image to golang 1.22 to match the current state of the code.
