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
1. Support for adding labels and annotations to functions & environment via fission CLI through create & update command.
2. Change ensures labels and annotations assigned to the environment would reflect on pods created via executor type pool manager and new deploy.
