feat(device): 1n-alt ansible improvement

We're seeing extra IGMP traffic which interferes with tests which must
be disabled. This is done by disabling the setting by default on all
interfaces.

The default setting is also adopted for other traffic-related
configuration:
Default sets the configuration when the interface is created. For
hardware interfaces, that is at boot time. For VF interfaces, when we
create them with the csit-initialize-vfs.sh script and for virtual
interfaces when they're created.
On the other hand, the all configuration option doesn't set the
configuration. It uses the current configuration value along with the
passed configuration value to produce a new value, which could be
expressed as:

f(old_value, value_from_all) -> new_value

Where f is a function specific to each configuration option. Using all
thus requires us to know the function and the old value which is less
reliable than just using default everywhere.

Also fix the 1n-alt VF init script.
