Add Data Source Check For Resource

[RyanDerr]

Overview

The goal of this smaller PR is to assert that only data sources should be generated if there is a matching resource for the boundary terraform provider that already exists. This facilitates us to make so that data sources such as auth-tokens and sessions are not generated, as likely that are not useful to provider a data reference to.

Changes

• Add a method to determine based on the resource paths from the openapi json, if an associated resource of the same type already exists within the provider, if not then skip generating that data source.

Notes

Because not all data sources map perfectly 1-1 with resources, in order to determine if a resource *likely exists globbing is performed in order to check if a resource for the provider exists. An example of this would be data source host_catalog vs the resource boundary_host_catalog_static.
