Add all the rest of the pipelines
Add all the rest of the pipelines

These are all of the rest of the v2 pipelines.

Also, removed reverify from check and added the require-approval stanza
from v2's check.

The experimental pipelines are included even though we don't actually
need them in v3 with job-dependencies, to ease migration.

The silent pipeline was omitted, as it's not currently used.

The email settings were included and uncommented, as we should start
figuring out if email is broken.
