This is mostly intended to be used for waterfall/trybots. Fuchsia-on-metal isn't available as a Swarming dimension, so in order to run tests, use QEMU-with-KVM on the host. It might also be useful for local development for those without a Fuchsia hardware device. Bug: crashpad:196, crashpad:212 Change-Id: I88170bc95bd532676b787b50a94f7fa3c69b1ac7 Reviewed-on: https://chromium-review.googlesource.com/822523 Commit-Queue: Scott Graham <scottmg@chromium.org> Reviewed-by: Mark Mentovai <mark@chromium.org>
