Now inline supports all three variants:
- a single inline map (backward compatibility for config patches).
- a list of inline maps
- raw bytes, that can also contain multiple documents.
`omnictl cluster template export` command was updated to export config
patches/manifests as raw bytes to ensure that multiple values are
properly supported.
