json-output: Omit unchanged resource_drift entries
Previously, if any resources were found to have drifted, the JSON plan output would include a drift entry for every resource in state. This commit aligns the JSON plan output with the CLI UI, and only includes those resources where the old value does not equal the new value---i.e. drift has been detected. Also fixes a bug where the "address" field was missing from the drift output, and adds some test coverage.
