RFID check with individual location check

[frezik]

The current RFID check only says if the given key is available or not. We need a call that can tell if an individual scanner should allow the given user. For instance, if the fob holder is allowed in the office, or turn on the laser cutter, etc.

The route is:

/v1/rfid/location/:rfid/:location

Tasks:

• Add a description to the openapi doc
• Add the route to the router
• Add a new table for locations
• Add a new table that relates locations to the RFID tag that is allowed to use the location
• Add a method to the DB interface to check if the RFID tag is allowed to use the location
• Implement that method in both PG and Mock databases
• Implement the route
• Unit tests for the route (with Mock database) and directly against the PG database

Also, make sure the entry log page is updated to show the location.
