Remove terraform-plugin-sdk/v2 Dependency

[bflad]

terraform-plugin-testing version

1.5.1

Use cases

This issue is a placeholder for removing the github.com/hashicorp/terraform-plugin-sdk/v2 dependency. The terraform-plugin-testing Go module was created with the explicit goal of being an easy migration from using the equivalent testing functionality of the github.com/hashicorp/terraform-plugin-sdk Go module, but that meant keeping compatibility to support helper/resource package TestCase and TestStep type Providers and ProviderFactories fields which directly implement sdk/v2 types. This sometimes indirect dependency on sdk/v2 can cause issues like #185.

Proposal

Those fields, and any other potential usage of sdk/v2 types, should be deprecated in a 1.x release with the goal of removing the dependency in the 2.0.0 release of this Go module.
