Update manifest protobuf to include optional hash for operation blobs.

In order to support downloads over http for a number of reasons, we need
to secure http downloads. Among other things, we reduce the attack surface
by adding an extra hash for each operation that uses a blob. This CL
adds this extra field in the update_engine metadata protobuf. Checking this
first so that subsequent CLs that populate/consume this field in
delta diff generator and update_engine can be developed independently.

BUG=chromium-os:33602
TEST=Tested on ZGB to make sure existing functionality works fine.
