> In HIVE-13090 we decided that we should not close the metastore if there is an unexpected
exception during the expired token removal process, but that fix leaves a running metastore
without ExpiredTokenRemover thread.
> To fix this I will move the catch inside the running loop, and hope the thread could
recover from the exception
