[yocto] Reducing nightly/release build artifacts.

[Flanagan, Elizabeth]

Folks,

I'd like to start looking at reducing the number of artifacts we're
releasing both for our nightly builds (which is at 250,000 artifacts
and .25 TB!) and releases.

What I'm thinking is this:

Reduce nightly:
- Reduce ADT-REPO to just qemu* arches for all builds
- If every QA team could provide me a list of what files they actually
need I could reduce the published artifacts to *just* what is needed.

Reduce releases:
- Reduce ADT-REPO to just qemu
- Don't release ipk/rpm/debs. Continue to release ipks through ADT
- Don't release machines outside of BSP tarball /binary directory

If folks who do QA could get me a list of all the files they use, we
can start removing excess artifacts. I know this is a balance, but I'd
really like us to start targeting our release artifacts to just the
things we need.
