This fixes up most of inconsistencies related to pylint runs in
  order to clean up and make test pass (mostly)

   This reduces the code duplication reusing API to test alarms

    Those 2 scripts lack unit test

   * Use single API
   * Unify usage of _simulateScript with the mixin

  This script is a copy the one on product/ERP5/bin/bigfile_client_example.py

   By respecting the dependencies, it is possible to use it on development
   environments to speed up a bit the setup.

    Maximum Invoice Delay defines the delay after due date
    Maximum Invoice Credit defines the max amount after the due date before stop the instances.

  Upgrade dump configuration to help to detected long ago local changes that
  can eventually can exist on production sites.

   * Add tests for SubscriptionRequest_processStarted
   * Add tests for SubscriptionRequest_verifyInstanceIsAllocated
   * Added test for SubscriptionRequest_processConfirmed

    It was rewritten to use a simplified shared API from the Test Mixin
