RDBDocumentStore now also supports the conditional remove operation, but only limited to conditions on the _modified field.

> The DocumentStore API allows for conditional inserts (only add document if not present yet) and updates (using findAndModify() with a condition), but it doesn't allow you to remove a document given some conditions are met.
> This feature is required to make sure the VersionGarbageCollector does not remove document that are modified concurrently. See OAK-2778.
