[lilic]

Rename the CLI flag namespace to namespaces.

The merging of this is blocked until after the v1.9.0 release.

Hey @lilic. Can I take this up?

[lilic]

@raunaqness go for it! Thanks! Note that it won’t be merged until the current release candidate is released. So a week or two. :)

/assign @raunaqness

@lilic Thanks!
I'm a little new to open source contribution, can you guide me a little bit about where I should start looking for to make the changes for this?

[lilic]

Just search wherever it says namespace in CLI flags and rename to namespaces. https://github.com/kubernetes/kube-state-metrics/blob/master/pkg/options/options.go#L88
