[VDSM] build-artifacts failing on master

[Nir Soffer]

The build-artifacts job is failing on master now with this error:

19:09:23 Error: NOSE is too old, please install NOSE 1.3.7 or later
19:09:23 make[1]: *** [tests] Error 1

19:09:23 RPM build errors:

Looks like this patch is the cause:

commit 4e729ddd2b243d0953e2de5d31c42fc59859bf23

    build tests: Require NOSE 1.3.7 and up for running tests

    On RHEL7/Centos7 the provided NOSE version is 1.3.0.
    CI runs the tests with 1.3.7.

    To be consistent and avoid different behaviours, assure that the tests
    are running with a minimum nose version of 1.3.7.

    Specifically, between 1.3.0 and 1.3.7 a bug has been resolved regarding
    test labeling and its support with test class inheritance.

I did not check the details, but it seems we need to revert this patch.

Please check and fix.
