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

* Migrate HPA v1 to v2beta2
HPA v2beta2 is defined and supported from 1.19+ onwards.
Also HPA v2 is stable from 1.23 onwards. As we support 1.19+
onwards using HPA v2beta2.
This change is base for custom metrics support we want to add
later by modifying Function spec.
* Add unit tests for hpa operations
* Use constants instead of strings

Using interface makes it easy to create a fake client and unit test
a specific portion of the code. We should be able to more write unit
test and increase coverage of code with this change.

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.
Before this PR, CLI functions fatal out when encountering error
instead of returning it. Such behavior makes it hard to reuse
the functions nor writing unit tests. This PR aims to make functions
return errors instead of error out.
