Cleanup:
- Debug comments removed
- Log entries for debug removed

Unique change:
- The instantiation of ScalabilityRunner doesn't work with a node_test_suite, so now it uses the testNode (self) directly.

Cleanup:
- Old code comments removed
- Debug comments removed
- Old log entries for debug removed

Overall summary of changes:
- The base of this code comes from some work done by Rafael in here:
    https://lab.nexedi.com/nexedi/slapos.toolbox/blob/master/slapos/agent/tester.py
- Minor refactoring in communication with slap objects for supply and request.
- New setters (they will be refactored soon)

Cleanup:
- Old code comments removed
- Debug comments removed
- Old log entries for debug removed
- Minor refactoring for readability

Overall summary of changes:
- Most of the communication with slapos is done using the Slapos Master Communicator instead of Slapos Controller:
  * supply, request, check instance status, check software status.
- Refactoring of related methods (waitInstance, isSoftwareReleaseReady, etc.)
- Initialization of communicator: initialize connection to SlapOS usign key and certificate
- Some related imports added
- General refactor: some unnecesary sentences and methods were removed.

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.

Post is a comtainer which contains raw data without any metadata.
A post can be seen as any item send or received by an instant message application.
HTML Post is one type of post, which contains richtext in HTML and UTF-8.
Eugene Shen wrote a post system before, which inpired us. This bt5 is a
new implementation which under Tristan Cavelier's guide.

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).
