Adding speed limit options for DB auditor

Code Issues Proposed changes

Fix bug 1129760
Without speed limit, DB auditor will likely consume high CPU% on
storage node. That will highly impact the cluster's performance.
This patch adds two options for account/container auditor:
 - containers_per_second: Maximum containers audited per second
 - accounts_per_second: Maximum accounts audited per second
