Multiple outgoing interfaces with smart selection based on latency to destination network about psocksd

[clue]

Hi @ethaniel, I like this idea! 👍

send out pings […]

Sending out pings (ICMP echo requests) requires root privileges, so I'm not sure this is something that many people would like to use :)

Here's my suggested alternative:

When a new connection is being established, send […] through all available network interfaces (that will be the primary connection + the VPN connection) […] establish the outgoing socket through the faster interface. It adds a little overhead to every new connection, but the resulting speeds can be faster.

In other words: We can concurrently try to open the connection through multiple connectors and just pick the fastest connector. Note that this will (wastefully) open quite a few TCP connections that are not needed, but depending on your needs you may or may not notice this.

In the future, we may look into adding some kind of smarter heuristic to pick the right connector to begin with, however I'm not sure what we should base this on.

In the meantime and/or as an alternative, you may also (manually) set up separate rules for your common services where you know which connector is the fastest.

The required connector has been implemented via clue/reactphp-connection-manager-extra#10

This means this could now be relied upon here.

My main issue currently is how should the user configure this behavior?

I still think that this feature makes perfect sense 👍 However, there are currently no immediate plans to build this from my end (no demand at the moment and more important outstanding issues currently), but I would be really happy to accept PRs 👍
