Refactoring Cloudiscovery CLI to support [provider] [resource] format

[jacorbello]

The purpose of this PR is to refactor the CLI to support multiple cloud providers. The changes proposed here will provide benefits in the following manners:

• The argparser has been updated to nest subparsers under cloud providers
  • (aws | az) (vpc | security | etc.)
• Allows for future standardization of resource arguments (not part of this PR)
  • Instead of provider-specific resource calls, generalize them:
    • cloudiscovery aws network --vpc-id vpc-xxxxxxxx
    • cloudiscovery az network --vnet-name my-vnet

Note - This is a breaking change for any automated implementations of Cloudiscovery. Commands such as aws-vpc and similar are no longer supported in this refactor.

This is to be the first of a series of pull requests to begin enabling multi-cloud provider support.

Might have been the change in version number, I forgot to update the git tag as well. Just updated that and pushed the tag up. Maybe that'll help? 🤷
