Was discussed offline, I'm not a big fan of this and changing the driver dialects. Ideally, we should be maintaining the lifecycle of ThreadPoolExecutors. This way, it won't be shut down when a destructor is called on the wrapper while the executor is being garbage-collected.

Went with the simpler solution, just remove this is_closed check.

Description
Previously, MySQL would sometimes hang because we use the executor when we call the
is_closedmethod when we call the destructor of AwsConnectionWrapper. However, when we call the destructor, it's not guaranteed.By submitting this pull request, I confirm that my contribution is made under the terms of the Apache 2.0 license.
