narrowwirepeer: rename expandnarrow capability to exp-expandnarrow The expandnarrow functionality lets a client have a shorthand (for Google it's a reference to a checked-in file) for a set of includes and excludes. For testing we should probably implement a simple version of that functionality here. For now, rename the capability so we don't burn the good name in the future if we need to change behavior. It's plausible that this functionality should be dropped from the narrowhg we ship long-term, but I'm dubious as it seems pretty likely other organizations will want similar shorthands for commonly-used subsets of their trees.
