html_last_updated_fmt option is interpreted as a
byte string in python3, causing Sphinx build to break.
This patch makes it utf-8 string.
Changing Popen to .check_output because of 3 reasons:
1. check_output() will raise CalledProcessError if
the called process returns a non-zero return code.
2. For consistency with keystone [1] and cinder [2]
3. It makes the code look much better.

This consists of a duplicate of the [nova-]api-ref setup and
conf.py along with tooling to fail the tox -edocs target when
a route that is defined in
nova.api.openstack.placement.handler.ROUTE_DECLARATIONS is not
present in placement-api-ref/source/index.rst.
tools/placement_api_docs.py will report which routes are missing.
Though completely gameable (as demonstrated in the current lame
index.rst) it's better than nothing and provides some useful
structuring on what to do next. It's also the case that the 'docs'
target in tox is not part of gating.
The response for GET / is in place with the necessary
parameters.yaml for it to be correctly described. The 'get-root.json'
file provides the JSON of the expected response. The expectation is
that later commits will add information for other urls and their
JSON files will be named method-path-separated-by-dash.json with a
request/response qualifier as necessary.
Followup patches will add other routes.
A new parameters.yaml is used instead of reusing the one from
api-ref as there isn't a lot of expected overlap and having a
separate file will ease eventual extraction.
Running tox -eplacement-api-ref will generate the docs for review,
with output in placement-api-ref/build/html/index.html.
This will be hooked up with CI to deploy the generated docs,
eventually.
