Add passthrough-default-server-ping option

[BBaoVanC]

If passthrough-default-server-ping is set to false, then Velocity will respond with its own MOTD and version for pings that go to a host not listed in forced-hosts. This means that you can make it so Velocity has its own generic network-wide MOTD which is shown on the proxy's main IP(s), but also see the backend's MOTD and version if connecting to it specifically (using a forced host).

This option doesn't have any effect if ping-passthrough is disabled.

Rebased because of the addition of enablePlayerAddressLogging, I think this is ready for review

Can conflicts be resolved and then this merged this would be a great feature

[BBaoVanC]

Would be nice to know if this has a chance at being merged directly to Velocity (I hope it can) first, before I spend time rebasing it but yes

I’m putting this, and any other PR that changes something in the config, on hold. We absolutely need a config rewrite before this gets merged. Changes like this to the old system are simply unsustainable now

Any idea when this rewrite will happen for the config
