InferencePool helm chart flags setting is not user friendly

[nirrozenbaum]

the flags section of the InferencePool helm chart is currently modeled as an array instead of a map.
that means that if one wants to set a single flag, the options are either to use a values.yaml file, OR to use indexed array of values, e.g.,:

--set inferenceExtension.flags[0].name=<MY_FLAG> --set inferenceExtension.flags[0].value=true

This is an non user friendly UX and is not as expected.
the expectation is to be able to set a cmd-line flag intuitively using:

--set inferenceExtension.flags.<MY_FLAG>=true
