Also, expose and document unicity score divisor.

This fixes many different bugs, like random Unauthorized errors when a
knowledge pad is deleted.

When an object is created, calling immediateReindexObject is only a performance
coding crime, which should be negligible since pads are objects that are not
created often. Previous implementation was certainly even less scalable due to
the many extra requests done to wait that new pads are indexed.

If immediateReindexObject is too slow, a distributed cache could be used
instead. This is not trivial and overkill for the moment.

It would be better if we didn't have to rely on the catalog. IOW, data could
have been organized differently so that in ZODB, pads are grouped in containers,
1 per user.

so that :
* the result is stable.
* no permission is required for Supply and Resource only for price calculation.
* no proxy role is required in script.

Because the method internally overrode 'uid' after the first group of objects,
passing a list of uids could make it go berserk and activate all objects in
catalog with an uid greater than those of the first group.

Although searchAndActivate was not initially written to be called with such
list, this commit fixes this instead of forbidding conditions on 'uid',
since it remains useful to easily split & group activities.

Funny things can happen if you have multiple machines and their clock are not

Add Business Template with Constraints as a example of bt5 with all configuration required to upgrade

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 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.

The logic of all Configuration Items was not changed, but now the
changes are applied only if fixit is True and the constraints are
filtered by constraint type equal configuration.
