RAZ-549: As a user I want to share a file URL with an expiration date
- Added date pickers for expiry date field
- Tweaked scheduled task to check and add in 'Asset has expired' label for hosts that are missing it
- Remove renditions, versions and sharing tabs for assets if asset has expired
- Removed basket, favorites, email and download icons for expired assets in all views
- Renamed scheduled task by prepending 'w_' to prevent login screen for it
