rats_install scheduling disabled

[Kamil Paral]

After discussion with hongqing I disabled rats_install test in commit 531830e. It is too
outdated and doesn't currently work. Hongqing plans to update it in the future and
then we can re-enable it.

    rats_install: disable scheduling
    
    This test is outdated and doesn't work at the moment. We need to update
    it first. Untill then let's keep it disabled.
