Remove Namespace creation limit for non-k8s env (#52)

There is legacy Kesque code that limits the number of namespaces a user can create when running with an environment other than K8s. These limits no longer apply.

I tested this by running setting `running_env` to `web` and then testing with `npm run serve` before and after this commit. It works as expected.
