shill (chromeos): Enables new ProgressiveScan field trial groups

We'll be trying a couple more progressive scan algorithms (the previous
ones were fine but we're experimenting) and this CL enables those
algorithms as new field trial groups.

The finch study tests a new algorithm, called progressive scan, for
scanning for wifi access points.  The study compares scan times for
various progressive scan parameters versus those for a conventional full
scan.
