nodemap: move the main switch to the `format` section

The config to enable persistent nodemap is now `format.use-persistent-nodemap`.
However the option remain marked as experimental because it only improve
performance for people using the rust extensions.

# Dummy extension that adds a delay after acquiring a lock.
#
# This extension can be used to test race conditions between lock acquisition.
