Upgrade async package to 3.2.2 (#8447)

* Revert "Revert "Bump async to 3.2.2 (#7618)""

This reverts commit 75153a555211d654744c2e61e27fe21085826c22.

* [web] fix usage of async.queue.drain in script

* [clsi] fix usage of async.queue.drain

* [spelling] fix usage of async.queue.drain

* [redis-wrapper] fix usage of async.queue.drain

* [web] Test that LockManager queue is cleared

This protects against a regression found when upgrading the
async package. Here we test that the `queue.drain` callback
is really getting called, and the lock is being removed from
the LOCK_QUEUES map.

* [redis-wrapper] Upgrade async to 3.2.2
