leigh capili 6c6c98c9ca Refactor loops over SupportedMediaTypes() where mediaType is used to match a single SerializerInfo{}
We have an existing helper function for this:  runtime.SerializerInfoForMediaType()

This is common prep-work for encoding runtime.Objects into JSON/YAML for transmission over the wire or writing to ComponentConfigs.
