According to https://nose.readthedocs.io/en/latest/#note-to-users

> Nose has been in maintenance mode for the past several years and will likely cease without a new person/team to take over maintainership. New projects should consider using Nose2, py.test, or just plain unittest/unittest2.

Moreover,
> nose supports python3. Building from source on python3 requires distribute. If you don’t have distribute installed, python3 setup.py install will install it via distribute’s bootstrap script.

So, even sources of `nose` are built with `2to3`.

Thus, this package should be removed from Sisyphus. Eventually, it will be broken anyway.

fix guidelines:
- package required `nose` at runtime should be updated/removed or drop this dep
- package required `nose` for buildtime tests should be updated/removed or drop this dep/disable tests

Current status:
runtime reverse deps: 56
buildtime reverse deps: 245
