Mistakenly the computing team merged two specs in nova that actually
targeting the placement service. Placement has its own specs directory
to store these. So this patch adds the these specs to the placement
repository.
The only change in the two specifications compared the ones approved in
nova-specs repository is the removal of the note from the top that they
are targeting placement service as it is now obvious.
