Add PullRequestResource functionality for updating labels and comments.

Missing from this change: * Statuses, since this might involve more discussion on the set of statuses that we want to support. * Updating from changes to the raw payloads. Unclear how we want to handle these at the moment. Punting on this for now. First step for supporting #778.

+
+## Generic pull request payload
+
+The payload generated by default aims to abstract the base features of any
+pull request provider. Since there is no one true spec for pull requests, not
+every feature may be available. The payload is output to `$PATH/pr.json` and 
+looks like:
+
+```json
