This PS updates all Deckhand documentation to be sphinx-compliant so that it can be rendered into HTML automatically for hosting. This PS also removes deprecated/redundant/unhelpful documentation and upates README to a bit more informative and helpful. The design.md file has been broken up into different sections with deckhand/docs for easier consumption. Change-Id: I44afcd22a7f5f05e44563342bb98b30fd806f598

Rest API Policy Enforcement
Policy enforcement in Deckhand leverages the oslo.policy
library like all OpenStack projects. The implementation is located in
deckhand.policy. Two types of policy authorization exist in
Deckhand:
- Decorator-level authorization used for wrapping around
falcon"on{HTTP_VERB}" methods. In this case, if policy authorization fails a 403 Forbidden is always raised.- Conditional authorization, which means that the policy is only enforced if a certain set of conditions are true.
Deckhand, for example, will only conditionally enforce listing
encrypted documents if a document's metadata.storagePolicy
is "encrypted".
Policy Implementation
Deckhand uses authorize from oslo.policy as
the latter supports both enforce and
authorize. authorize is stricter because it'll
raise an exception if the policy action is not registered under
deckhand.policies (which enumerates all the legal policy
actions and their default rules). This means that attempting to enforce
anything not found in deckhand.policies will error out with
a 'Policy not registered' message.

Sample Policy File
The following is a sample Deckhand policy file for adaptation and use. It is auto-generated from Deckhand when this documentation is built, so if you are having issues with an option, please compare your version of Deckhand with the version of this documentation.
The sample configuration can also be viewed in file form.
