Botond Dénes 4ab4619341 auth: common: separate distributed query timeout for debug builds
Currently when running against a debug build, our integration test suite
suffers from a ton of timeout related error logs, caused by auth queries
timing out. This causes spurious test failures due to the unexpected
error messages in the log.
This patch increases the timeout for internal distributed auth queries
in debug mode, to give the slow debug builds more headroom to meet the
timeout.
