Support full resource names in autokey_config.folder

Add pre_* custom code to drop the 'folders/' prefix from API requests,
as well as a diff suppressor for the same reason. The ID also needs to
be adjusted on post_create.

Side change: add a time delay after setting the autokey_config in the
basic example, to try to address test flakiness (#18935)
