Sample Failed Step: viz_browser_tests

Sample Flaky Test: FolderShortcuts/FilesAppBrowserTest.Test/traverseFolderShortcuts_DriveFs

Original change's description:
> Run more FilesApp tests with DriveFS enabled.
> 
> Run with DriveFS enabled:
> - Drive-related context_menu.js tests.
> - Drive-related metadata.js tests.
> - folder_shortcuts.js tests.
> - fileDisplayDrive in tablet mode with DriveFS enabled.
> 
> In order to make those tests pass:
> - Pass capabilities metadata to FakeDriveFs in SetMetadata() and return
>   it in GetMetadata().
> - Populate croppedThumbnailUrl so metadata cache doesn't retry fetching
>   metadata, trying to get a value for it.
> - Remove two unused and incomplete tests in context_menu.js.
> - Only perform early-init for the downloads volume for the "user"
>   profile.
