DT-1273: Remove `oneOf` from locations

[HenrikHL]

Change all location objects:

• remove oneOf from all Location objects
• all previous posibilities in the oneOf have now been "converted" to optional properties
• it will now be possible to define a location using more than one type of Location-Type
• examples updated accordingly
• AddressLocation object deleted
• FacilityLcoation renamed to Facility and the properties locationName, locationType and UnlocationCode have been removed
• UNLocationLocation removed
• GeoLocation added and used in Booking ShipmentLocations
• Location object created insteaed of having it inline inside ShipmentLocation
• LoadLocation and DischargeLocation updated with the new pattern

The above fixed in Booking, EBL, Issuance and PINT (Interoperability)

EDIT: added DT-1328 to EBL, ISS and PINT since a geoCoordinate was already added to BKG
