Let the cluster take decision about how activities will be running.

Sale Order and Sale Packing Lists can have uncommon, migration related specialise.

Invoice shall have only correct specialise.

Share and improve common logic: if Business Process does not provide links for
rule's trade phase do not apply.

ERP5Type_getSecurityCategoryFromAggregateMovementItemByComputerPartition has to
be splitted because Software Instance should only have at most one setup
packing list: it is not possible to migrate an Instance on another Partition!

The use case is: delete (rename) and create clone.

Ticing invokes alarm. But this test needs ticed (for indexation) documents
without any alarm begin run.

So use stepRequestComputerPartitionNoTic and provide stepCleanTic in order to
have tic without any side effects.

Hardcode values for PPL too.

Subscription Item typoes (like Hosting Subscription) are not supported as
explanation passed to builder.

Instead just generate Applied Rule path globbing passed to builder.

Do not try to edit if not needed.

Invoices has no causality.

Inner joins can return duplicate lines in some cases.

Do small batches.

Additionally lower registration priority in order to minimise duplicates.

Also make activity per person.
