framework/replay: Add support for download caching proxy
Add a new replay run option '-c' or '--download-caching-proxy-url' that allows to provide caching proxy URL in order to reduce the time required for downloading the trace files.
This is used internally as a prefix for the URL specified via '-u' or '--download-url'. E.g.: http://caching-proxy/cache/?uri=
