The order in which messages are returned by getMessageList is undefined,
and manageInvoke refuses to execute messages which are blocked by their
dependencies. Notify depends on Alarm_runUpgrader, so it must be explicitly
ran second.
Also, avoid listing activities twice.

Here, we expect exactly two activities, one of each type, and just do not
rely on these being listed in any order (...in theory, as this is actually
assumed by the next iteration on getMessageList, but this is a separate
issues).

Documentation says this step is done in one transaction, so implement
this as documented.

Detecting developer mistake and automagically running this step in smaller
transactions if more than 100 documents seems unnecessary. At least, it
contredicts documentation.

now that we use alarm sense method, another `notify` call is activated

erp5_upgrader: TemplateTool_checkCategoryNameConsistency constraint can update categories which have moved

test.erp5.testUpgrader.py: the bt5list update in afterSetup() includes the case of several business templates locations

test.erp5.testUpgrader.py: update the bt5list in afterSetUp(). Otherwise the user has to invoke genbt5list manually before runnning the test. It was also confusing, because the same test would pass in the server but not locally

Active process detail is a list of strings.

The problem with callMethodOnObjectList is that when an object can't be
processed, all other objects of the same group fail without any chance to
be retried separately.

Grouping is configurable with usual CMFActivity parameters in new 'group_kw'
parameter, to avoid any conflict with catalog parameters (**kw).
'packet_size' and 'activity_count' are still accepted for backward
compatibility.

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
