Use Kubernetes Client instead of Controller APIs from CLI (#2605)

Use the Kubernetes and Fission Client from CLI instead of Controller API.
This removes port-forwarding for the controller across Fission CLI mostly.

* Use configurable client in CLI
* Move resource namespace under cmd client
* use server to get fission version
* get archive with URL
