Location header should be sent with an HTTP status code of 201 or 202

[Lucas Alvares Gomes]

The HTTP Location header should be sent when a new resource is created (201) or when a server accepts the request and will process it asynchronously (202).

201:
To provide information about the location of a newly created resource the Ironic API should return the URI for the new object in the HTTP Location header.

202:
After the server accepts the request it needs to return an URI in the HTTP Location header so that clients will know how to track the status of the request.

Currently WSME has a bug opened about it[1], but the Ironic API we could workaround it by editing the pecan.response.location object directly before returning.

    Return the HTTP Location for newly created resources

    To provide information about the location of a newly created resource
    (201) the Ironic API now returns the URI for the new object in the HTTP
    Location header.

    A new function build_url() was created in the link.py by factoring out
    part of the the Link.make_link() method so that we can reuse that part
    of the code to build a URL without having to create a new Link object.

    Return the HTTP Location for accepted requestes

    After the server accepts a request (202) it now returns an URI in the
    HTTP Location header so that clients will know how to track the status
    of the request.
