Connectivity: honor binding attribute 'region_configuration_id'

[cbarbian-sap]

Describe the Problem

If using a connectivity proxy in multi-region mode, clients have to set the SAP-Connectivity-Region-Configuration-Id header with each request; for example, when using destinations that means setting the property URL.headers.SAP-Connectivity-Region-Configuration-Id in the destination.

The connectivity:lite binding now seems to have an (optional?) field region_configuration_id, such as

"region_configuration_id": "cf-eu10-canary”

In Kyma/Kubernetes context, people can inject that attribute into the binding via the usual btp-service-operator binding templating capabilities.

It would be nice if Cloud SDK would recognize this attribute (if present, as fallback if the header is not set).

Propose a Solution

If a destination does not have the according header set, but the used binding does have the region_configuration_id attribute, then use it for the requests sent to the connectivity-proxy endpoint.

Not a must but could improve the overall usage experience.
Probably also applicable for the Java Cloud SDK.
