1. Add explicit indication that the output is produced by SHOW EXPLAIN/ANALYZE FORMAT=JSON command. 2. Remove useless "r_total_time_ms" field from SHOW ANALYZE FORMAT=JSON output when there is no timed statistics gathered. 3. Add "r_query_time_in_progress_ms" to the output of SHOW ANALYZE FORMAT=JSON.
