Timeout on commands for remote servers

[grtjn]

Most commands in Roxy go through the Roxy::Http library. Some commands can take long however, and get canceled from client-side by a default read timeout in that library. It defaults to 120 seconds, which can be too low.

The default should be increased (240 or 300 sec).

It would also be great if it were possible to add some property in one of the property files to override that default, maybe something like http.read-timeout=300
