@sameer79 Or we could make it simple for now that the status icon means
whether the interpreter restarting operation is successful just as what this PR
did now IIUC. One concern is that when the restarting operation is failed,
what user would get in frontend besides the red status icon. Because I think
red status icon is not sufficient for users, user don't know what to do for
this kind of failure. At least, frontend should tell user what's wrong in
restarting interpreter.
