First commit with all my changes in webrunner-testnode in order to run the benchmark suites using performance tester and runScalabilityTestSuite.
Full of logs, comments and hard-codes.
Cleanup code needed.

- Functionality in Slapos Master Communicator setters for instance name and request parameters moved to request method.
- Refactoring to avoid calling request method with hardcoded states.
- Refactoring in supply method: state parameter removed.

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

Overall summary of changes:
- No changes were made

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.
