Description

TestKeySpaceManager#testExpiredOpenKey is flaky.

In testExpiredOpenKey we are opening four keys for writing and wait for them to expire (without committing). Verification/Assertion is done by querying MiniOzoneCluster and matching the count. Since the cluster instance of MiniOzoneCluster is shared between test-cases in TestKeySpaceManager, we should not rely on the count. The verification should only happen by matching the keyNames and not with the count.
