Create promise.cfg when during unit tests

 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.
