Provide ability to configure number of days leadtime before a move date can be requested.

A lot of customers need X days notice before a move can be coordinated and scheduled. It would be very helpful to automatically disable dates from a calendar selection based on this setting. This will prevent users from selecting a move date of 'tomorrow' if the move team requires 5 days notice for planning and coordintation.

Might even be helpful to have this at a building by building level
