Add Script Constraint document, view and actions

Also, Added constraint property sheets to Script Constraint portal type
Rename _build to _checkConsistency to follow Constraint API

Also, the logic of all Configuration Items was not changed, but now the changes are applied only if fixit is True.

Cosmetic: Trailing whitespaces were removed in the same commit
Add test to simulate the issue with the method TemplateTool.installBusinessTemplateListFromRepository

Using the method try to install Business Templates that are already
installed, the Business Templates is uploaded on ERP5 but not used. It
creates a lot of garbage because in the end you have many bt5s not
installed.

Also, Improve error message
inherit Base for reuse methods fixConsistency / checkConsistency
Simplify erp5_upgrader to be possible upgrade any project just enabling the alarms that all Constraints will be called and fixed.

The alarms were renamed to cover each step of upgrader and give the possibility to call each step manually one-by-one. Also, all Scripts that the logic can be done by installing Business Template was removed.

Also added:
 - Constraints that can be used in the upgrader
 - Unit test to check different scenarios
 - Extend external method to be possible dump workflow chains to be compared with all configuration defined on Business Templates
Add Business Template with Constraints as a example of bt5 with all configuration required to upgrade
Clean up the code to a Folder not call checkConsistency recursively
Add ConstraintType property sheet to all constraint portal types
Improve code because is not needed call fixConsistency twice
Base.checkConsistency: s/error_list2/extra_error_list/
Add constraint to be possible call checkConsistency recursively to specific portal type
Add new constraint to be possible call checkConsistency recursively
Enable checkConsistency recursive to Accounting Transaction
[erp5_upgrader] Enable checkConsistency recursive to Leave Request, Group Calendar, Group Presence Period and Presence Period
[erp5_base] Set RecursiveCheckConsistencyConstraint to Person
Missing commit workflow chain definition
Consider the error list only when fixit is False
Print list to try to understand a random failure
Print the repository list to try catch a random failure
runUnitTest script: Avoid set duplicated paths on repository list
