We occasionally receive bug reports from users of VSCode-go and GoLand. GoLand has its own way of capturing the packet exchange between itself and delve but VSCode-go (supposedly) doesn't. So far this hasn't been a problem since all bug reports were obvious bugs on the plugin or easy to reproduce without VSCode-go, but it might be helpful in the future to have a way to log the packet exchange between dlv and a frontend. This commit adds a --log-output option to enable logging of all rpc messages and changes service/rpccommon accordingly.
