Add fprocess to generated CRDs and fix indentation

Notes from @alexellis:

• The faas-cli generate command was not importing the required environment variables such as fprocess - so the env function store image for instance was failing to deploy via faas-cli generate --from-store env
• Indentation for generated YAML and the $HOME/.openfaas/config.yaml file were both being set with spaces instead of the more usual - a visual thing, but also four spaces looks unusual for Kubernetes YAML
