OVV - Create integration-code to fetch data from remote

[olebhansen]

This task is to code the API-calls to BR/OVV to fetch data (i.e. read-only / one-way-synch FROM BR/OVV).
Part of this task should be to "solve" how to do incremental and batched updates.

Regular triggering of this integration for the purpose of keeping our replica in synch, is in task #206

Future support for write-operations will be part of #201

1. OVV- Get Credentails for OVV endpoints #205
   +0
   
2. Configure OVV credentials
3. Feature/job: initial dataload
4. Feature: incremental/delta-updates

To be decided: what to do if the full/delta difrentiation is not as easy as just starting at 0 and incrementing a counter.

Acceptance criteria:

• Our code can call the OVV API and get a sucessfull response back (i.e. with data)
