* Use SubscriptionId throughout TestResources
Fixes#1454
* Resolve PR feedback
* Default DeleteAfterHours to 48 for SDK team
Also makes a few other adjustments for subscriptions, like restoring the previous one if available and another was specified.
* Resolve PR feedback
* Change deployment mode to Complete
Also fixes an issue where if the user opted not to deploy to the same resource group, the script would continue execution anyway.
