Make all functional jobs non-voting

Currently functional jobs are all broken because of recent bump of
cinder client. Since we need fix for both heat and heat-tempest-plugin
repo this change first make all functional jobs non-voting to unblock
any change in heat-tempest-plugin repo until the fix is merged in heat.
