[dashboard] Integration tests depend on Openstack lab images

[Ekaterina Chernova]

Currently we do have this code in setUp class

cls.demo_image = cls.get_image_name('demo', image_list)
cls.linux_image = cls.get_image_name('linux', image_list)
cls.windows_image = cls.get_image_name('windows', image_list)

Need to figure out, how image could be upload from tests.

Also, it could be used in tests with images.
Currently (https://review.openstack.org/#/c/106767/19/functionaltests/sanity_check.py) the first image in the list is choosed for that test

    Refactor functional tests

    * Reduce amount of time waiting for element that doesn't exist
    * Improve some xpaths
    * Fix screenshot taking to happen only on fail
    * Add config file to .gitignore
    * Testcase for checking integer field was removed since
      it checks library code, not Murano
    * Generates test package archive with different fqns
    * Use muranoclient insted of request module
    * Maximaze browser window before test execution
    * Use consts.py instead of common.ini to keep xpaths

    After this patch app-incubator is not needed for test run
