This is a partial revert of Id8e1e84cd3717dfd0a3b3f80acec50f96c205251
The policy.d infrastructure was not previously tested anywhere real,
and turns out that it completely invalidates the caching of policy
files. Using policy.d means that nova-api makes > 33k reparses of the
policy files during a gate run.
There is no straight forward fix at this point in the cycle given
various library freezes in oslo. Instead we should revert using the
policy.d directory and merge those rules back into the policy.json
file.
