> In order to replace the {{mesos-fetcher}} binary with the {{uri::Fetcher}}, each plugin must be able to determine/estimate the size of a download.  This is used by the Fetcher cache when it creates cache entries and such.
> The logic for each of the four {{Fetcher::Plugin}}s can be taken and refactored from the existing fetcher.
