Implement Cloud Provider Hierarchies as Classes

[jsoconno]

Is your feature request related to a problem? Please describe.
No.

Describe the solution you'd like
There should be the ability to use child classes of the Cluster class that are aligned with cloud provider hierarchical structures. For example, in Azure you can have Azure > Management Groups > Subscriptions > Resource Groups > Virtual Networks > Subnets. These should be classes you can call rather than having to use the generic Cluster object.

Describe alternatives you've considered
You could just use Cluster, but the benefit to hierarchies is it would be very clear what the container was for. It could also provide some opportunity for extendability in the future. For example, if architectures were modified to create a stock template Terraform configuration output.

Additional context
None.
