Make Horizon Dashboard settings operator overrideable.

We want to allow operators to override Horizon's default settings. This involves moving local_settings.d out of the read only snap filesystem, and into $SNAP_COMMON. This is a little bit tricky. First, we patch settings.py and local_settings.py as we're building the snap, to include a LOCAL_PATH in $SNAP_COMMON. Then, we add a template with the rest of our default overrides, and write it out to $SNAP_COMMON/horizon/local_settings.d Finally we tweak our tests so that we can give our overrides a spin. As a bonus, this makes test_horizonglogin.py a lot easier to run in our multipass testing scenario! `tox -e basic` now also runs selenium tests, as well.
