Configuration needs

The idea is to delete all resources in the existing reservation and add new resource / extra with the value of the paid amount. Therefore we need to create the following items:

1. Ledgers 
   1. Outstanding voucher amount
   2. Collected voucher amount
2. Holding report group
   1. To be defined by resort, so it can be made available in Microstrategy / Powerplay reporting
3. Extra's (description to be decided by the resort)
   1. 'Corona voucher previous booking' 
   2. 'Corona voucher collected' 
      1. Both extra's will need to have:
         1. Ledgers as per 1
         2. Customizable amount
         3. Holding report group
         4. Full rentability
         5. rate with 0 amount, as will be adjusted to the paid amount via the script
