[Serve] `serve run --reload` to auto-recover during a fatal failure

[Gene Der Su]

Description

Currently when serve run cli is called with --reload flag, Serve will keep the session alive, watch any file change, and redeploy with the changes. However, if there is a fatal failures with the file, the loop will break and shutdown serve. Ideally we should catch fatal failures and keep serve running until user hit control+c. Let's add a try-except block around the reload function and only break out loop if keyboard interrupt is raised.
