* Refactor provider validation into separate func & recurse
Refactors the validate provider functions into a separate function
that can recursively search above a module to check and see if
any parents of the module contain count/for_each configs to be
considered
Validate providers in expanding modules. Expanding modules cannot have provider configurations with non-empty configs, which includes having a version configured. If an empty or alias-only block is passed, the provider must be passed through the providers argument on the module call
