Description of problem:
Information about variant doesn't get passed down to test cases using SNAKE templates. This results in broken test cases which rely on this information. See below:

The everything-package-set template is supposed to generate:
%packages
*
-@conflicts-<variant>

The template looks like this:

$ cat everything-package-set.py 
from pykickstart.version import FC6, RHEL6
from installdefaults import InstallKs

# minimal install, procedural style
def ks(**context):
    '''Package set / Everything'''

    ks=InstallKs()
    if ks.version <= FC6:
        ks.packages.add(['@everything'])
    else:
        ks.packages.add(['*'])

    conflicts = "@conflicts"
    variant = ""

    if (ks.version >= RHEL6):
        if context.has_key('variant'):
            variant = context['variant']
        elif context.has_key('VARIANT'):
            variant = context['VARIANT']

    if len(variant) > 0:
        conflicts = "@conflicts-%s" % variant.lower()

    ks.packages.add(['-%s' % conflicts])

    return ks


When scheduled with:
bkr workflow-snake --arch x86_64 --variant Workstation --distro RHEL6-6.0 --snakeserver=snake.devel.redhat.com --template everything-package-set --task=/distribution/reservesys

The generated ks.cfg contains only -@conflicts which is wrong. This results in file conflicts in the transaction. 


I'm marking this as regression because it was working previously, we've used it during RHEL6.0.
