Improve code because is not needed call fixConsistency and checkConsistency twice

Clean up the code and keeping the funcionality to not return any error message if raise Unauthorized
Remove external method because is not working in slapos environment and calling this is only stopping the intance instead of restart
Add script and extend external method to be possible dump workflow chains to be compared with all configuration defined on Business Templates
add Script Constraint actions, view and actions
Add constraints that can be used in the upgrader

Also, add unit test to check different scenarios
Extend method to be possible filter constraint by contraint_type
Add Business Template with Constraints as a example of bt5 with all configuration required to upgrade
Remove constraint used only to test.

This constraint is not generic enough to be kept
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.
