Deprecate older data tables

Deprecate and cleanup code related to older data table versions

[Jackie-Jiang]

We bumped the default data table version in #10543, which is not released yet. I don't think we can remove the support for old data tables right now because that can cause the system not able to upgrade. If we are running new broker and old server, broker won't understand the data table sent by the server, and our upgrade sequence is controller -> broker -> server.

+1 we recently found out that we are running on an older data table version and started upgrading the version. Removing support for older data table versions will be a major backward incompatibility change.
