Gian Merlino 5048ab3e96 Add metrics to the native queries underpinning SQL. (#4561)
* Add metrics to the native queries underpinning SQL.

This is done by factoring out the metrics and request log emitting
code from QueryResource into a new QueryLifecycle class. That class
is used by both QueryResource and the SQL DruidSchema and QueryMaker.

Also fixes a couple of bugs in QueryResource:

- RequestLogLine start time was set to `TimeUnit.NANOSECONDS.toMillis(startNs)`,
  which is incorrect since absolute nanos cannot be converted to millis.
- DruidMetrics.makeRequestMetrics was called with null `query` on
  unparseable queries, which led to spurious "Unable to log query"
  errors.

Partial fix for #4047.

* Code style

* Remove unused imports.

* Fix tests.

* Remove unused import.
