* protocols: Derive Serialize for versioned generic responses

This allows for serializing the output of as_original(). We cannot also
derive Deserialize here because the enums use references to the inner
types, which is unavoidable in the current implementation because
as_original() takes a reference to self.

* cli: Add the output mode options

This allows selected whether to use CommonResponse or the original
response struct when outputting.

* cli: Fix ExtraRequestSettings docs showing up in help output

* cli: Add help headings for timeouts and extra request settings
