Reviews API

[TsPG128]

I have extended the API with reviews. Current calls supported:

GET /V1/reviews (method getList)
GET /V1/reviews/:reviewId (method get)
POST /V1/reviews (method save)
DELETE /V1/reviews/:reviewId (method delete)

For it, I created a ReviewsRepository, along with interfaces for Review and ReviewSearchResult.
The GET /V1/reviews call supports searchCriteria.
I have put the restrictions to the 'Magento_Review::reviews_all' privileges on all of the calls.

I guess a bit of cleanup in the ReviewInterface itself should be still done, for what data should be returned and posted.

Additionally, I've created a setter function for status, that is setting the status id in the review based on the status code, along with a getStatus function, that is returning the status code based on the status id in the review.

Parts that are in the same module but not done are: ratings, summary, status calls.
Tests are not done yet too for it.
