getLocalRolesGroupId does not exists on portal type.

Order Builder has same functionality as Devliery Builder.

Returning true allows to add movements to existing one, and this group shall
always separate them.

Show sorted list, as sorting does not impact sets equality, and, if possible,
format a list in human readable way.

Do not *reset* them, as it is normal to have more then one Open Sale Order
with same reference, as other coordinates (like validation_state) are used
to distinguish the documents.

smtp_url can be None, so do not treat it as string, allow to take different
actions (like doing nothing).

getMessageList shall not be available on normal mail host. It will be available
on one coming from live tests, so in such case die immediately.

This reverts commit 4e0c2786.

Catalog clearing functionality is required.

The promise will always fail, unless there is active system preference to fix.

This is yet another case of object being already removed.

Use aq_base to only fetch from document.

The logic of assignments checking shall be easy to use by other plugins in
order to avoid code duplication and minimise risk of non fixed security issues.

Avoid calling isDivergent which can take few minutes to finish.

causality_state comes from well designed causality workflow, which informs
enough about delivery state. Fetching causality_state property is extremely
fast.

 Scope only includes cloudooo, memcached and kumofs configuration for
 now.

 Create promise configuration on-the-fly with the configurations reusing
 existing API to get cloudooo, memcached and kumofs informations from
 environment.

 This approach allow us use erp5_promise alarms at any unit test to
 configure cloudooo, memcached and kumofs, instead implement ad-hoc
 configurations on tests afterSetup methods.

 Ignore alarm if promise is not defined (not the contrary).
