[features request] Add a command to restart language server just like restart a typescript language server

[shynome]

The same as #2324

Today I use vscode to develop a golang project , and find I am so in need this features if without it just can kill language server in task manager and wait vscode restart the language server

the best developer also can't catch various situations, like move a go file to another package the language server can't know how to do and I lose tips , why not give the language server a choice to restart

BaseLanguageClient exposes a start() method, and LanguageClient exposes a stop() method. I'm assuming a command could use those to restart the underlying language server. Would anyone be willing to confirm that?
