RTA : test run preparations for IFW 4.7.0

Local files:

1. Check the url where latest installer files reside, for example:
http://ci-files02-hki.intra.qt.io/packages/jenkins/tqtc-installer-framework/4.6/stable/

2. then check /home/<user>/git/tqtc-qt-rta/suites/shared/objects/product_qtifw.py:70

self.http_files02 = self.http_files02 + "tqtc-installer-framework/4.6/stable/" <-- that this url represents the same folder than in the url above.

3. Check that there is .ini -file available for the version in question in:
/home/<user>/git/tqtc-qt-rta/suites/shared/data/QtIFW/46.ini

Check and modify both files if needed.

Jenkins setup:
