Login screen redesign (CL 1)

The goal is to make the single user login screen look the same with the new
design, without worrying much about the extensibility / reusability.

Please refer to

All browser tests passed.

Fix two container issues for new login screen

1) We need the outer-container to be scrollable when gaia screen and
virtual keyboard are shown together, so the dark overlay ('login-shield')
should always have the same size with the larger one of
the outer-container and the scroll-container, otherwise we see areas
without overlay when scrolling up.

2) We should remember to clear contents on the small pods container
before rebuilding pods.

In the blur mode, do you only show the wallpaper layer?
we might have a fast path for wallpaper blur, I want to make sure you have a the same use case as here:  bug 738185 

I think it's the same use case. It's the same with this: https://cs.chromium.org/chromium/src/ash/login/ui/lock_screen.cc?q=setbackgroundblur&dr=C&l=83

I guess before login, there is no any apps so you always see the wallpaper?

I think tbarzic@ is working on lock screen apps that will hide the wallpaper on lock screen. 

wzang@, could you try the ToT code to turn on blur on the login page.
Thanks.

Please use this function to set blur for login/lock screen:
SetLayerBlur()

I'm working on it. Thanks!
