Use ProxyUriManager in ProxyServlet

Swtiches ProxyServlet, by way of ProxyHandler (and ProxyBase, to a lesser extent) modifications, to use ProxyUriManager.

The implementation follows the now-typical pattern of a UriManager's make/process methods.

Where is the handling of REFRESH_PARAM now?

Down in ProxyUriBase, with method translateRefreshStatus handling the logic
involved in setting caching headers (taking into account noCache, uri return
status, the refresh param, and passed-in defaults).
