Please document & announce merge proposals workflow for the ProposedMigration hints

[Dimitri John Ledkov]

Dear Release team,

Please document on https://wiki.ubuntu.com/ProposedMigration something
along the lines - What to do if tests have regressed/broken in the
release?

And explain that one should write hints and make merge proposals
against the ubuntu-release file.

Also please explain the supported hints and their format. I've managed
to construct some of them, but it is a bit fragile / non-intuitive.

Also do a one-off announce on ubuntu-devel@ mailing list that hints
overrides should be done as merge proposals and not ad-hoc IRC pings
on #ubuntu-release, with copy & paste of the new doc section about it.

Since merge proposals, appear to be much easier to discuss / review /
queue process, and have history available about them.

This is a crucial bit that is missing from ProposedMigrations
documentation, and I think lack of docs/advertisement on "how to make
hints changes happen" affects many developers and should be publicized
/ re-advertised more widely.

Dimitri.
