Code Issues Proposed changes

Update placement aggregates spec to clarify generation handling 

This adds a paragraph to the placement-aggregate-generation spec to
clarify that in older microversions, the generation of the resource
provider will not be updated. We considered updating it whatever the
microversion but it turns out that there's extant code relying on
the old behavior.

Details of representation changes can be found below.
When requests are made at an older microversion, thus not including the
generation in the request, the generation of the resource provider will *not*
be updated in the database. This is because there is existing code in Nova
which currently relies on the generation not being updated. If Nova has it
then there could easily be code elsewhere.
