Instances related to the HS are already assignor on it.

Check that destroyed state creates no new object (test_request_destroyed_state).
Check that simple case of requesting two different instances works correctly
(test_request_two_different).
Check that changes to tree structure are applied correctly for indexed tree
(test_request_tree_change_indexed) and that they are forbidden in other cases
(test_request_tree_change_not_indexed and test_request_tree_change_same_transaction,
where the former is a low severity bug, so expectedFailure).
Check that state is correctly propagated (test_request_started_stopped_destroyed).

 BT5 list was sorted accord the dependency tree of vifib_erp5, this list
 will be automatically resolved in future.

 List was obtained by the output of:
  context.portal_templates.resolveBusinessTemplateListDependency(["vifib_erp5"])

Prove that trying to request with same title will fail (test_request_sameTitle).

Prove that shared parameter is correctly supported and system complains in case
if its type is incorrect (test_request_shared_True and test_request_shared_unsupported).

Prove that indexation will not result in damaged system (test_request_unindexed).

Prove that in case of normal request with same coordinates same instance is returned
(test_request_double).

Prove that in case if there is damage in system (same tree contains one then
more instance with same title) no more requests will be allowed (test_request_duplicated).

Jump directly into proper inital state of the tree.

Simply move from vifib_erp5 to slapos_erp5.

Software Release document is created on demand.

variation_category_list is redefined in this property sheet.

This bt5 is not needed as fiber request is not installed neither.

Move its code into slapos_cloud and vifib_web bt5.
