Integration test of Bearer Token pass-through (CPS-2126 #5)

This covers REST endpoints of GET, POST, PUT, PATCH, DELETE
of /ncmp/v1/ch/{cmHandleId}/data/ds/{datastoreName}
and the async REST endpoint of POST /ncmp/v1/data

It verifies that:
- bearer token is passed from NCMP to DMI
- basic auth header is not passed from NCMP to DMI
