[jira] [Created] (ARROW-16607) [R] Improve KeyValueMetadata handling

Neal Richardson created ARROW-16607:
---------------------------------------

             Summary: [R] Improve KeyValueMetadata handling
                 Key: ARROW-16607
                 URL: https://issues.apache.org/jira/browse/ARROW-16607
             Project: Apache Arrow
          Issue Type: Improvement
          Components: R
            Reporter: Neal Richardson
            Assignee: Neal Richardson
             Fix For: 9.0.0


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
