Matt Riedemann 519e5a22d1 Implement granular policy rules for placement
This adds a granular policy checking framework for
placement based on nova.policy but with a lot of
the legacy cruft removed, like the is_admin and
context_is_admin rules.

A new PlacementPolicyFixture is added along with
a new configuration option, [placement]/policy_file,
which is needed because the default policy file
that gets used in config is from [oslo_policy]/policy_file
which is being used as the nova policy file. As
far as I can tell, oslo.policy doesn't allow for
multiple policy files with different names unless
I'm misunderstanding how the policy_dirs option works.

With these changes, we can have something like:

  /etc/nova/policy.json - for nova policy rules
  /etc/nova/placement-policy.yaml - for placement rules

The docs are also updated to include the placement
policy sample along with a tox builder for the sample.

This starts by adding granular rules for CRUD operations
on the /resource_providers and /resource_providers/{uuid}
routes which use the same descriptions from the placement
API reference. Subsequent patches will add new granular
rules for the other routes.
