Adding the ability to use Locators

[msmakouz]

In the Entities and Embeddings generators, the logic for searching for classes with attributes is moved to separate locators. Now they only accept the locator interface and don't know anything about the implementation. This will allow these generators to be used with different implementations searching classes with attributes.
