> Followup to ARROW-15271. Among the objectives:
> * Push KVM handling in ExecPlan so that Run() preserves the R metadata we
> want; also remove the duplicate handling of it for Write()
> * Better encapsulate KVM for the the $metadata and $r_metadata so that as a
> user/developer, you never have to touch the serialize/deserialize functions,
> you just have a list to work with
> * Factor out a common utility in r/src for taking cpp11::strings (named
> character vector) and producing arrow::KeyValueMetadata
