server.address required in JSON-RPC over stdio anonymous pipes

What's the problem?

As of #2503, the server.address attribute is required in JSON-RPC client spans. However, there is no server address if JSON-RPC is used over anonymous pipes.

One such scenario is that the JSON-RPC client starts the JSON-RPC server as a child process whose stdin and stdout are connected to pipes.

Describe the solution you'd like

server.address should be recommended or conditionally required, rather than strictly required.

@KalleOlaviNiemitalo i just took a look and it appears that this attribute has actually been required for alot longer than the specified pr and in fact it has been required since 5b8861e#diff-a4272fe55d12584e896526953d110354d9cc0c4ee26c6cdf559cbafdd50d9cea. The difference is the json-rpc document is now self sufficient rather than being an extension of the general document.
