Fetch Mandoline components from Google Storage as needed.

Fetch Mandoline components from Google Storage as needed.

Proof-of-concept for fetching optional components.
Return LocalFetcher redirect URLs for missing components.

This uses NetworkFetcher to access Google Storage files:
https://pantheon.corp.google.com/storage/browser/mandoline/

For example, delete pdf_viewer.mojo locally, and run:
$ mandoline http://www.pdf995.com/samples/pdf.pdf --predictable-app-filenames

TODO: Integrate with planned Omaha fetcher and updater work.
TODO: Support fetching apps with resource files.
TODO: Handle broken URLs. (unavailable component files, etc.)
TODO: Avoid kPredictableAppFilenames switch? (need executable bit set)

BUG=479169
TEST=Mandoline can fetch the pdf_viewer as needed.

Patchset #9 (id:160001) has been deleted

[msw, 2015-11-20 00:53:34]

Hey Ben, I'm using a new 'latest' directory on our Google Storage bucket instead
of trying to use chrome/VERSION numbers. This should unblock some
experimentation while we work on component versioning in parallel. Take a look
at the updated CL as you have time; thanks!
