[Feature Request] Network-wide support for auth-command

[Vagor96]

It would be helpful to support execution of the /auth command from any server within a Velocity network, rather than requiring to join the specific server on which the Authentication plugin is installed.

From my point of view, there are two potential solutions:

1. Move the authentication logic to the proxy, allowing /auth to be handled centrally.
2. Add MySQL support to the authentication plugin, along with a configuration option to disable the embedded web server on non-primary instances. The primary instance could then poll the shared database for changes made by other servers.

Supporting server networks is certainly something that I would like to do. And indeed do it by using a shared mysql database and secondary instances. No ETA on when this would be implemented though.
