DwC Auth Token not available (DwC + IAS)

Issue Description

This is an issue between DwC and SAP Cloud SDK's integration for "Principal Propagation" scenario when DwC is using IAS for authentication.

I think originally SAP Cloud SDK had approuter in mind. So it would expect an "Authorization" Header in the incoming request header. For DwC, it keep this dwc-ias-jwt token in the header in case needed. This dwc-ias-jwt token is the one I should use as "Authorization" header which later on can be passed onto remote service as user_token(x-user-token) for token exchange and authorization(principal propagation scenario). But SDK is not able to retrieve this dwc auth token and continue with the rest of the work.

After some research, I find this issue looks a lot like https://github.com/SAP/cloud-sdk-java/pull/337. However, I think that fix was targeting DwC xsuaa token key (dwc-jwt). For the case of DwC+IAS, the key would be "dwc-ias-jwt".

I have prepared a PR to enhance https://github.com/SAP/cloud-sdk-java/pull/337 so that dwc-ias-jwt will be covered as well.

Important information:

Your code

public HttpDestination getBusinessLoggingDestination() {
Try<Destination> tryGetDestination = DestinationAccessor.tryGetDestination(BUSINESS_LOGGING);

if (tryGetDestination.isSuccess()) {
   HttpDestination httpDestination = tryGetDestination.get().asHttp();
   logger.debug("business log url: {}",httpDestination.getUri());
   return httpDestination;
}

try {
  var options = ServiceBindingDestinationOptions
    .forService(ServiceIdentifier.of(BUSINESS_LOGGING))
    .withOption(BtpServiceOptions.BusinessLoggingOptions.WRITE_API)
    .onBehalfOf(OnBehalfOf.NAMED_USER_CURRENT_TENANT)
    .build();
  HttpDestination destination = ServiceBindingDestinationLoader.defaultLoaderChain().getDestination(options);
  DestinationAccessor.prependDestinationLoader(
    (name, option) -> name.equals(BUSINESS_LOGGING) ?
    Try.of(() -> destination) :
    Try.failure(new DestinationNotFoundException(name))
  );
  return destination;
} catch (Exception e) {
  String message = "Failed to get destination for business-logging caused by: " + e.getMessage();
  logger.error(message);
  throw new IllegalStateException(message, e);
}
}

Expected outcome The token exchange will be conducted successfully.
Actual outcome "Failed to get the current user token" error was thrown.
Steps attempted to resolve the issue The root cause is dwc-ias-jwt in header is not picked up by the SAP Cloud SDK as a auth token. Used a workaround to prove the case as below:
```
RequestHeaderAccessor.setHeaderFacade(new DwCCdsRequestHeaderFacade(context.getCdsRuntime()));
```

private class DwCCdsRequestHeaderFacade implements RequestHeaderFacade { private final CdsRuntime runtime;

DwCCdsRequestHeaderFacade(CdsRuntime runtime) {
  this.runtime = runtime;
}

@Override
public Try<RequestHeaderContainer> tryGetRequestHeaders() {
  final String DWC_IAS_JWT = "dwc-ias-jwt";
  final String bearerPrefix = "bearer ";

  return Try.of(() -> {
    final Map<String, String> headers = RequestContext.getCurrent(runtime).getParameterInfo().getHeaders();

    logger.debug(String.format("dwc-ias-jwt contained cdsruntime? %s", headers.containsKey(DWC_IAS_JWT)));
    logger.debug(String.format("dwc-ias-jwt in DwCCdsRequestHeaderFacade : %s", headers.get(DWC_IAS_JWT)));
    Map<String, String> heads = new HashMap<>(headers);
    heads.put(HttpHeaders.AUTHORIZATION, bearerPrefix + headers.get(DWC_IAS_JWT));
    return DefaultRequestHeaderContainer.fromSingleValueMap(heads);
  });
}

}


- In case of issues with any of our VDMs:
    - What happens when a request is performed directly via an HTTP client tool such as Postman?
    - In case that succeeds please provide details on the request such as URL, query parameters, header parameters, prerequisite requests (e.g. CSRF token), etc.  
- Potentially missing information (open questions you might have)
