Currently, the default policy.json files for all projects are just
dropped into place. There is no flexibility to customize, edit or update
certain key-values in the policy.json. This change adds a custom module
called 'copy_updates' that allows any updates to be applied to the
default file.
Implements: blueprint dynamically-manage-policy.json
