evergreen runs all of the dbtest tests individually, but individual developers don't have a very good way of doing that. Now that passing the dbtests are required for pushing in the commit queue, it should be possible for developers to simply ensure that the dbtests are passing before pushing their patch to the commit queue.

Two things need to happen.

1. We need to fix dbtest so that it runs without failure in all-tests mode
2. We need to add a new evergreen task that runs dbtest in all-tests mode
