Swap in-memory logger to write stdout in post_save_hook

This commit makes the needed changes to inventory update
post_save_hook logic so that the historic log lines that
inventory updates write will be written to stdout,
but this hack bypasses the ansible-runner verbose event
logic and dispatches verbose events directly.

Fix the venv application with the ansible-inventory system
(note: much of this is undone in a later commit)

Deal with some minor test updates for
the ansible-inventory interface changes
