Initial configuration for customs.hmrc.gov.uk

This configuration is to accommodate vat notices to be scraped and imported, with document source of [this form](http://customs.hmrc.gov.uk/channelsPortalWebApp/channelsPortalWebApp.portal?_nfpb=true&_pageLabel=pageLibrary_PublicNoticesAndInfoSheets&propertyType=document&columns=1&id=HMCE_CL_000080)

There may be the need to add additional query strings params at a later point.
