Flow checkpoint diagnostics agent.

Description

Creation of a new tool ("the Checkpoint Agent") that provides checkpoint stack sizing diagnostics information.
Based on the experimental Kryo hook, the checkpoint agent intercepts Kryo flow checkpoint reads and writes, and prints a hierarchical view of the entire Flow Object stack with sizing information at each level.
May be used standalone and/or in conjunction with the recent CRaSH dumpCheckpoints command.

This tool was built following a troubleshooting event with a real corda network.
