B-59299 - Category refactoring

* Extends the Atom Hopper JDBC adapter to insert events of type "tid:" & "type:" into their own columns in the Postgres DB.
* Builds & packages an updated version of Atom Hopper which contains the CloudFeedsFeedSource & CloudFeedsFeedPublisher adapters for the updated DB.

* For the "tid:" prefix, this commit currently inserts the "tid:[tenantid]" into the generic categories column as well as [tenantid] into the tenantid column.  After 3 days and all entries have a populated tenantid column, CloudFeedsFeedSource will be updated to start reading the tenantid column & "tid:[tenantid]" will no longer be inserted into the generic categories column.
