Create an implementation class for IServiceAccountJwtClient in each cloud provider library
Multiple services might end up having the same implementation of IServiceAccountJwtClient (e.g. https://community.opengroup.org/osdu/platform/system/storage/-/blob/master/provider/storage-aws/src/main/java/org/opengroup/osdu/storage/provider/aws/util/ServiceAccountJwtClientImpl.java) to generate service account token at runtime. Moving the implementation to respective provider libraries will prevent this issue
