Switch pulse to run building and autotests using the modularized repositories

Most likely this can be realized this way:

1. Instead of using the modularization scripts to run autotests for all platforms, we switch to only one platform (the fastest, so probably Linux), and turn off autotests.
2. When the script runs, we instruct it to push its generated modules to the repositories on scm.
3. Pulse in turn will react to the pushing of the repositories and run autotests on them, according to the implementation of QTMODULARIZATION-55.

At least that's my suggestion. One possible concern is that many autotests will run multiple times this way.
