[Feature]: Sigv4auth support for backend storage #7468
Description
Requirement
I work in an AWS environment, and as a result we use managed Prometheus. I would like to use it as a storage backend for SPM, but to connect to it, you need sigv4auth, which is not currently supported in Jaeger.
Problem
The storage backend for SPM is not compatible with sigv4auth.
Proposal
I would like sigv4auth to be added, given that the extension is already present in opentelemetry collector contrib.
