Before this change, a read of size (let's say) < 10, into a buffer of size 10, will return EOF because we're using CopyN to limit to the size of the buffer. That resulted in the body being read from later, which should only happen if it couldn't fit in the buffer.
With this change, the body is properly NOT set when it can all fit in the buffer.
* reverseproxy: Add more debug logs
This makes debug logging very noisy when reverse proxying, but I guess
that's the point.
This has shown to be useful in troubleshooting infrastructure issues.

Ideally I'd just remove the parameter to caddy.Context.Logger(), but
this would break most Caddy plugins.
Instead, I'm making it variadic and marking it as partially deprecated.
In the future, I might completely remove the parameter once most
plugins have updated.
* reverseproxy: Close hijacked conns on reload/quit
We also send a Close control message to both ends of
WebSocket connections. I have tested this many times in
my dev environment with consistent success, although
the variety of scenarios was limited.
* Oops... actually call Close() this time
* CloseMessage --> closeMessage
