Cache OTA manifest in update_engine
When resuming download of an OTA package, update_engine needs to
redownload the manifest of OTA package, located at beginning of file.
However, the manifest blob can be as large as ~150K for some updates.
This CL caches manifest on disk, so that update engine no longer has to
redownload the manifest for every resume.
Test: Perform OTA, pause and resume, verify that update succeeds
