Subject: [PATCH] qe: `--enable-playground` automatically enables graphql
 protocol (#4711)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If protocol is not specified explicitly and `--enable-playground` flag
is used, engine will default to GraphQL instead of JSON.

Close #4679
