Entities can be given identifiers by other organisations when they suscribe to their service. This identifier can be seen as a contact, as it will be used to reference the entity in all further exchanges. As the number of suscription can be unlimited, creating a new property for each kind of identifier becomes heavy, but customizing contacts using getIdTranslationDict is easy.

As a real life use case, in UK, a company which is allowed to instruct direct debits to their customer bank accounts is given a Service User Number, which should be transmitted with all direct debit instructions.

Since !306 we have configured system preference to use cloudoo from the Slapos SR, but this configuration was still old style configuration setting host / port.

It caused a test to fail 
```
======================================================================
FAIL: test_01_PreferenceSetup (testIngestion.TestIngestion)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/srv/slapgrid/slappart7/srv/testnode/aai/soft/f030becfa6e3878c62ccb9bccc43a291/parts/erp5/Products/ERP5OOo/tests/testIngestion.py", line 1048, in test_01_PreferenceSetup
    self.assertEqual(preference_tool.getPreferredOoodocServerAddress(), conversion_dict['hostname'])
AssertionError: 'erp5-cloudooo' != 'localhost'
```

and that was a problem with the test, we don't have to care about `getPreferredOoodocServerAddress`, as only URL matters now (it was just working because both were set to localhost).

- The conversion server is supposed to be configured in a system preference,
  so do this instead of using a normal preference.
- _getConversionServerDict -> _getConversionServerUrl, to make clear that
  cloudooo is now configured by a url, instead of a host/port couple.
- Refactoring: From the moment where setUpERP5Site() sets up things
  automatically, we don't the "same" duplicated code throughout many test to
  redo cloudooo configuration.
- In the promise file, the volatile/persistent memcached url were swapped.

configuring host / port was still compatibility
