cli: hardcoded namespace used for configmap fetch

[Peter Fern]

What steps did you take and what happened:

Starboard operator is installed in the starboard-system namespace.

When attempting to initiate a scan from the CLI, the starboard configmap is always fetched from the starboard context, ignoring the --namespace arg:

kubectl starboard --namespace starboard-system -v 10 scan kubehunterreports

What did you expect to happen:

The CLI should respect the provided namespace when retrieving the configmap.
