[TODO] support planning for destroy

[ITProKyle]

Summary

Creates a plan whose goal is to destroy all remote objects that currently exist. This can be useful for situations like transient development environments, where the managed objects cease to be useful once the development task is complete.

The idea for this implementation is based around terraform apply -destroy.

Tasks

• add --destroy option to runway plan
• add handling for passing options like this to deployment/module processing (e.g. <instance>.plan(destroy=True)
  • may need to be part of context
  • may need to be translated to a different command on the backend that calls a specific class method (e.g. .plan_destroy())
• modify module handler classes as needed once the design is finalized
  • for the first pass, just log that its not supported
• add --destroy logic to CDK
• add --destroy logic to Cloudformation
• add --destroy logic to Kubernetes
• add --destroy logic to Serverless
• add --destroy logic to static site
• add --destroy logic to Terraform
