## Description 

This PR enables logging of queries that time out. The logging uses the
`error` macro together with a new error code, `REQUEST_TIMEOUT`.

Note, that the timeout extension function was switched to `parse_query`
+ `execute`. Execute one takes care of the time, parse query takes care
of stringifying up the query (including resolving any passed, fragments,
etc).

## Test Plan 

Existing tests, manually checking for errors when setting a small
(500ms) timeout.
