The edge proxy stuff should be relatively trivial to implement. I think
this is mostly just replacing the trivial flow token in the received
parameter with one generated a la the algorithm in RFC 5626, Section 5.2
and putting it into the user part instead of a parameter.

New module parameter "use_flow_token" and a new function
add_path_token() and you are even backwards compatible. (Although I'd
probably have use_flow_token switch behaviour of the regular
add_path().)
