Configurations for the flutter framework repository (flutter/flutter).

The schedulers pull commits indirectly from GoB repo
(https://chromium.googlesource.com/external/github.com/flutter/flutter)
which is mirrored from https://github.com/flutter/flutter.

Try jobs use github directly but are also registered with luci-cq
to take advantage of led recipe builder tests.
