chromite: Add som-dispatcher build config.

Add everything needed to create a new builder to generate all SoM
alerts from a single location. This includes new build config, builder
class, and active stage.

This stage constains code only trivially modified from the Report
stage. This will need further modification to handle all builds.

After this is in place and working, we'll remove SoM dispatch code
from the ReportStage, and stop running it on our build masters.

SomDispatcher: Allow failures to fail build.

Also stop creating a chroot, since we don't need it for this build.

chromeos_config: Add som-dispatcher to internal waterfall.

Define a new builder for the ChromeOS internal waterfall. This is
expected to allocate a build column for it, but not to setup a
scheduler (yet). Will require a waterfall restart to take effect.

This builder now exists, but has no build scheduler. I've just manually triggered a build for it. If it works, and we are satisfied with the results, I'll enable a scheduler to run the builds automatically.

This builder is being scheduled and completing runs about every 25 minutes.

report_stages: Remove Sheriff-O-Matic dispatching.

Now that we have the som-dispatcher builder, we no longer need to run
this process during the report stages of normal builders.
