[roller-configurator] Extend Jiri support
Some Jiri rollers perform operations that require access to the full
checkout, which in turn requires configuring the roller with a Jiri
manifest to tell it what to check out.
Allow projects to configure the Jiri manifest to use for roller
checkouts with a new top-level `default_checkout_jiri_manifest` field in
rollers.textproto.
