Joe D'Andrea 1e146b1499 Add locations to POST /v1/plans API

When determining placements for a related set of resources
via OpenStack Heat, there's no a priori knowledge of specific
location candidates. Thus the /v1/plans API never accounted
for them. However, when it comes to ad hoc placement of a
single resource (e.g., via OpenStack Nova), such knowledge
*does* exist. This is one piece of a three-part change (same
issue tracking ID).

Placement API v1 - CURRENT

Determines placement for cloud resources.

General API information

Authenticated calls that target a known URI but that use an HTTP method the implementation does not support return a 405 Method Not Allowed status. In addition, the HTTP OPTIONS method is supported for each known URI. In both cases, the Allow response header indicates the supported HTTP methods. See the API Errors section for more information about the error response structure.
