Move from go-yaml/yaml v2 to ghodss/yaml

Previously we were using go-yaml/yaml for unmarshalling yaml to
api models.
There's problem with some fields, for example pod's spec.hostNetwork,
it didn't work with 'hostNetwork' in the yaml file.
The root cause were that protobuf adds json name field metadata to
the pods.pb.go generated file, but yaml.Unmarshal doesn't use that, but
defaults to "all lowercase" field name.
Switched to use ghodss/yaml which converts first yaml to JSON
and then unmarshals to the model, and that's why uses right field name.
