The Eclipse Reviews plugin currently parses what types of reviews are possible
by parsing the javascript from a gerrit page load. This minor
improvement exposes the same information via json rpc that is provided
via the HTML.
Curl command to test:
curl --header 'Accept: application/json' --data-binary \
'{"jsonrpc":"2.0","method":"gerritConfig",id:2222}' -H 'Content-Type: \
application/json; charset=UTF-8' \
