Bookmark manager is a new opt-in feature that is enabled via the SessionConfig.

It is responsible for providing an up-to-date set of bookmarks to driver on session creation and database data access.

Driver provides a default implementation via BookmarkManagers.defaultManager. The default implementation keeps track of a single local driver instance bookmarks only. However, it supports 2 extension points:
- updateListener - a listener for new bookmarks
- bookmarkSupplier - a supplier of additional bookmarks

Javadoc includes more general details.
