[ZEPPELIN-696] Add notification system for AngularJS z functions

[doanduyhai]

What is this PR for?

Add notification system for AngularJS z functions. Now that we expose the z Angular object, we should also catch error/exceptions and display error messages properly to the user.

I changed a little bit the default settings for ngToast. Instead of having notifications on bottom right, I let the default value undefined.

For Interpreter page notification, I force the position to bottom right as before when using default config.

For z functions error messages, I choose to display notifications on top right corner because it's clearer. See screen capture

This is a sub-task of epic ZEPPELIN-635

We already have ngtoast for that

[doanduyhai]

Right, didn't know that we had ngToast. I never see it in action. Will remove angular-growl-2

Rebased from master, only JS change, can be reviewed and merged quickly.

Do you want me to add also a test in ZeppelinIT to test for the presence at the notification in case of error ?

[Leemoonsoo]

I have tested and working well.
Looks good to me.

@corneadoug Can you take a look, too?
