-- | Sets the url to use as the origin of propellor's git repository.
--
-- By default, the url is taken from the deploy or origin remote of
-- the repository that propellor --spin is run in. Setting this property
-- overrides that default behavior with a different url.
--
-- When hosts are being updated without using -- --spin, eg when using
-- the `Propellor.Property.Cron.runPropellor` cron job, this property can
-- be set to redirect them to a new git repository url.
