Method showStatus

pkg/cmd/codespace/create.go:458–517

showStatus polls the codespace for a list of post create states and their status. It will keep polling until all states have finished. Once all states have finished, we poll once more to check if any new states have been introduced and stop polling otherwise.

// states have been introduced and stop polling otherwise.
