Drop nose dependencies

Horizon test setting no longer depends on nose and related stuffs.
This commit cleans up nose related dependencies.

The change was made in horizon Rocky-3,
so horizon 14.0.0.0b3 is required at least.

Also drops unnecessary Django dependencies. There is no need to
install Django explicitly as it is a horizon dependency.
