Alembic does lots of new things. Provide docs for how to use this. We
also improve upgrade docs slightly, removing references to ancient
reviews that are no longer really helpful as well as calling out our N
-> N+1 constraint.

This adds a few more things to the upgrade checks
reference docs after getting questions about it
during the Stein release goal implementation from
other project teams:
1. Notes the high level set of steps for upgrading
nova in grenade and where nova-status fits into
that sequence.
2. Links to the oslo.upgradecheck library which
didn't exist when the original document was
written.
3. Adds a FAQs section with Q&A for several things
that have come up during the Stein release goal.

This adds some background, guidelines and structural
notes on writing nova-status upgrade checks.
This is intentionally written with some potentially
redundant information or nova developers as it's
also meant to be consumed outside nova as part of the
community-wide "upgrade-checkers" goal for Stein [1].
