#3634

Describe the solution you'd like
Create a new auth type in multiple data source, like basic and sigv4, which relays OSD logged in user auth info/header to data source when calling data source APIs

Describe alternatives you've considered
Support something similar to asScoped function in opensearch service, which applies to all data source calls. this alternative approach may conflict with user selected auth types

Additional context
N/A
