Modified the aws_secret_backend_role resource to accept the user_path…

… and permissions_boundary_arn arguments. Updated the resource's tests to account for the new arguments. Consolidated some duplicate code in the tests into functions. Removed the tests' dependency on AWS credentials because Vault doesn't interact with AWS during CRUD operations on a backend role. It will now be easier to run the tests on the aws_secret_backend_role resource. Split two large multiline strings into smaller strings to make it easier modify them. (hashicorp#781)
