In the process of phasing out the 'quattroshapes' source in favour of 'whosonfirst'
we will emit a warning to users so they can begin upgrading their clients.
In the interim we will automatically rewrite all requests for quattroshapes to whosonfirst.
@todo: this is only temporary
@see: https://github.com/pelias/api/issues/442
