In addition to the checksum.sri qualifier from remote api spec, Bazel includes it's own set of qualifiers to each FetchBlob requests. https://cs.opensource.google/bazel/bazel/+/master:src/main/java/com/google/devtools/build/lib/remote/downloader/GrpcRemoteDownloader.java;l=76-85;drc=618c0abbfe518f4e29de523a2e63ca9179050e94 This change adds initial support for the http_header qualifier as well as acknoledge the existence of bazel.canonical_id header (without actually using it). Relevant tests were also added to demonstrate the current behavior. In a future patch, we may start rejecting unknown qualifiers as recommended by the Remote Asset API spec and thus, flip the assertions in the test. See bazelbuild/remote-apis#301 for more info. Another change to consider in the future is support for custom url-specific header credentials. This is being proposed in Bazel via bazelbuild/bazel#23578.
