Merge lp:~james-w/linaro-image-tools/obey-include-debs into lp:linaro-image-tools/11.11

[James Westby]

Hi,

Here's the followup branch that actually obeys the include-debs setting.

We pass the include-debs setting as the new download_content parameter
that just determines if we fetch the contents, or just the metadata.

We tested that passing content=None FetchedPackages to that method in the
last branch, so this is just about plumbing the right bits together.

Thanks,

James

I had a good idea to make this simpler.

Thanks,

James

Looks fine to me.
