Improve logging

[johnstairs]

• Switching to zerolog for structured logging.
• Log entries are JSON-formatted by default but this can be overridden with a command-line argument.
• Log verbosity can be set with a command-line argument.
• Each request is assigned a request ID, which is added each log message associated with the request and is returned as an HTTP response header.
• Adding a log message when the server starts and has started listening on a port

Looks good. My only issue was that in the devcontainer the vscode user does not have write permissions in /go so build fails due to permission issues. A sudo chown -R vscode:vscode /go does the trick. I also see there is a golang group, but it is also not group writable in that folder, so maybe a tweak to that would work.

Will fix that in a separate PR.
