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

This PR moves fission CLI as closer as possible to kubectl command behaviour. We have improved namespace handling behaviour across CLI.
* add namespace param for fn and env
* use common fn for ns check
* update validation
* default namespace for httpTrigger, env and package, config and triggers
* use default ns
* add namespace filter to spec
* add forceNamespace flag
* set current namespace
* add default namespace in config
* add namespace specific destroy
* add all namespace in the list of resources
* add namespace as global tag
* use %s instead of %v
* add test cases for namespace
* use ns in get all functions
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.
