Add --lazy-mode to commands which may autostart a server
Add --lazy-mode to commands which may autostart a server

Summary:
If no server is running, you should be able to run `flow status --lazy-mode fs`, which will autostart a server with `--lazy-mode fs` set.

Oddly enough, we already basically supported this, but just had never added the flag.
