Use namespaced policies

[Subtletree]

Proof of concept for namespaced policies #101 #8

If this looks like something that will be merged, I'll finish up with:

• Finish tests (maybe slim down and just test namespacing rather than duplicating other tests and adding namespace)
• Add something to the readme.
• Update method comments

Updated minimum pundit version to 2.0 varvet/pundit#529

Is it possible to make this as optional? (Maybe enable/disable in initializers)
For example, we have resources under Api::V1 namespace (Api::V1::UserResource), but our policies are without namespace (UserPolicy), so I think this PR will break, or no?

@jpalumickas see the discussion in #101 — this PR will definitely not be merged as it currently stands ☺️

@valscion oh! thanks for info 😉 Is it possible easily to upgrade this gem to support Pundit v2? I don't think there was lots of breaking changes there?

Might be! I opened an issue to discuss this further: #103

[valscion]

Hi! I'll close this PR for now as this isn't the approach we would like to go with. Feel free to continue the discussion in #103.

Thanks for creating a proof of concept of this approach ❤️
