Date Restrictions on Hoteling and Room Reservations
For both Room Reservations and Hoteling.
Use case: when a building is getting decommissioned, the client wishes to permit reservations up to the building's final day of operations and no later. In other words, If the building closes on July 1, a user logging in on June 29 should be able to reserve for June 30 but not July 2.
Use case: when a building is coming online, users should be able to reserve rooms on the day it opens before that day. If the building opens on July 1, a user logging in on June 29 should be able to reserve for July 2 but not June 30.
Use case: a room or building will be closed for a brief renovation i.e. painting. We should be able to set blackout dates while keeping the room available for booking outside those dates. If the building will be closed from on July 1-31, a user logging in on June 29 should be able to reserve for June 30 and August 1 but not July 2.
Admins should be able to set these dates per-room, or set them for all rooms on a floor or building.

This idea should follow https://spaceiq.uservoice.com/forums/925339-archibus/suggestions/48548615-hoteling-reservations-limit-to-working-days and be complementary, since both of them are useful.
