doc: placement upgrade notes for queens 

This adds a mention of the nova-scheduler service requiring
placement 1.17 and also links to the placement upgrade notes
from the more general upgrade notes, since we are now firmly
in a place where placement needs to be upgraded before nova.

Since we consider placement global, this removes the 1.14
note about nova-compute since we assume that if you're going
to upgrade placement to get 1.17 for the scheduler, and control
services should be upgraded before computes, then the computes
are going to get a new enough placement service automatically.
