Review comment:
Oh, we aren't using a shared metastore across test cases?
We should probably fix that eventually (maybe get this PR in first though).
We do want to keep the metastore around long enough that we detect Iceberg
connection leaks. Although it is annoying to have tests fail because the
metastore hangs, it's better than releasing a version that leaves connections
open and takes down a metastore.
