Consider adding back the removed 1.x classes for network override

The removed 1.x classes are documented on this [page](https://developer.adobe.com/client-sdks/resources/migration/android/migrate-to-2x/#network-override).

Start with the linked migration documentation for the network override and identify which removed 1.x classes are being requested. Determine the intended scope and acceptance criteria before locating the corresponding Kotlin implementation and tests; the work is done when the requested compatibility behavior and its coverage are agreed and implemented.
