DSU to support GSI key revocation list
DSU installation service fetches a key revocation list (key blacklist).
Revocation list is a https URL specified in a resource string.
Fetched result is cached in HttpResponseCache to save bandwidth, and the
cached result is always forced validated with server to ensure freshness.
In other words, fetching a revocation list is done via a "conditional GET",
such http GET returns a brief (304 NOT MODIFIED) response if ours cache is
still valid, else the server sends a (200 OK) response with new data.
TODO: Compare the installed DSU image's public key with the revocation
list and boot-ramdisk. If the public key is revoked then abort installation.
