The reason support * and allowing * by default is, to keep the same
behavior.
We already seeing many people asking about connection problem in various
environment.
Current origin autodetect routine
```
java.net.InetAddress.getLocalHost().getHostName().toLowerCase()
```
is not sufficient to cover many cases.
I think until Zeppelin gets better autodetect routine that covers most
cases automatically, we need to suppose * and make it default. Otherwise people
will keep asking and keep having trouble with configuring origin. Later we can
deprecate * and remove it finally.
Please consider this too.
