Add the possibility to use context with multiproxy environments in Velocity.

https://github.com/schematico/trevor/

The trevor project is a plugin similar to redisbungee but for velocity that helps sync playerlist and other things.
Adding support for this project might help the diffusion of Velocity proxy.

Ben's right - a context of server=name, when checked on a velocity proxy, will check against the proxy's name and not a subserver! Seems to me this is a suggestion for something that's already built in - closing, but please open a new issue that's a lot more specific on what your end-goal is, if your end-goal is not what you've stated here.

LuckPerms already has support for Redis messaging built-in, I don't see why this would be necessary for the moment.

I'm not talking about redis messaging, i'm talking about multiproxy environments in velocity.

At this moment if you have multiple proxys you can't specify a proxy context in luckperms.

Actually, you can. Proxy context is basically server=proxyname and world=servername. You can see #1668 (but yea its confusing)
