Allow xbusd to serve/distribute a compatible xbusctl binary
Created originally on Bitbucket by Anonymous
This could be served on the http gateway on a predefined url
This would allow:
- humans to easily download the correct xbusclt for a given xbusd instance
- xbusctl itself to auto-update if version negotiation indicates that the server is running a different version (this would need some user consent to avoid some corner cases)
