James E. Blair 9fa5fe4c31 Propose projects.yaml normalization daily
Add a job that will propose a change (or update a change) to
normalize projects.yaml, and run it once daily.  Normalization,
in this case, chiefly means removing un-used upstream lines
from projects.yaml (but will also catch minor YAML errors and
line wrapping).

Also simplify the proposal node regex.
