Commit 89a17f04 broke live tests using
ERP5TypeTestCase.publish when they are run from command line. Note that such
live test could not be run from ERP5.

More refactoring is needed because ERP5TypeLiveTestCase should only take care
of adapting ERP5TypeTestCaseMixin to an ERP5 environment, and runUnitTest
should never use it. Commit fd9219af looks a
wrong approach.

A change that also applies to traditional tests is that the password does not
need to be known when logging with basic authentication. If the given password
is empty (e.g. 'ERP5TypeTestCase:'), password validation passes regardless the
actual password: to keep things secure, this exception is only valid for the
test thread and during the call to publish(). This is a simple way to deal with
random passwords in live tests.

This results with calling correct methods on the server.

This hopefully fix the random issue of having test results not linked to
a project. Indeed, distributor/createTestResult was called in two different
times:
- by the testnode, with the project title
- by the runTestSuiteCommand, without the project title. This was
  not an issue most of the time, since the test result is already
  created. But if it was not there (like due to a cancelled test),
  a test result without project was created

erp5/tests/testERP5TestNode.py: Fix test_scalability_04_constructProfile. repository option is required for scalability test profile and it was added on commit 58d92a84.

erp5/tests/testERP5TestNode.py: Fix test_zzzz_scalability_19_xxxx. prepareFrontendMasterInstance was removed on commit 4048ab39.

erp5/util/testnode, scalability_test: Stop using a dummy frontend master and use host.vifib.net frontend with a valid SSL certificate instead. Always use https.

Conflicts:
	scalability_test/__init__.py

erp5/util/testnode: hosting subscription url was not updated once it was set. As a result, since testnode watched an old destroyed instance, the next test never started. Thus don't store hosting subscription url. It changes from time to time.

erp5.util.testbrowser: Refactor of openNoVisit() and {Image,Submit}Control for recent zope.testbrowser (followup of 5a0b3763).

Instead of sleeping, try using an API method until it stops raising
ConnectionError.

By using `os.path.normpath` we also support paths with a trailing slash.

- requests to bootstrap and site availability urls using a script run with userhosts
- hardcoded parameters removed
- try-exception controls in communication with master

This should fix the problem that `Revision History` is unusable on test
results because tests have a different name when they have been running
on different paths

This will be used to run tests using interpreter with pre-installed
eggs, generated with zc.recipe.egg's interpreter

- testnode saves in its config the repositories paths
- minor refactoring and cleanup
