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

The io/ioutil package has been deprecated as of Go 1.16, see
https://golang.org/doc/go1.16#ioutil. This commit replaces the existing
io/ioutil functions with their new definitions in io and os packages.

This PR adds an interface for controller API client, it allows us to
implement mock API client for unit testing with ease and we are
able to generate spec file without accessing the real Fission server.
