[cloud] [orc8r] [agw] Adding cleanup capabilities for Cloudstrapper

[arunuke]

Signed-off-by: Arun Thulasi arunt@fb.com

Summary

Orchestrator cleanup done via 'terraform destroy' might leave out some resources. This impedes future orchestrator re-deployments until these resources are manually cleaned up. The cleanup capability added to Cloudstrapper provides an automatic, customized way to cleanup an orchestrator deployment with or without an associated 'terraform destroy'.

Test Plan

A running orchestrator deployment was cleaned up by following the instructions available from the README file.

Additional Information

The cleanup capability can be used with a Cloudstrapper deployed Orchestrator and with traditionally deployed Orchestrators.

Most changes look good. Left a few comments. Also I like variables with underscores more than camelcasing here. But if this is the convention you have followed in other places in cloudstrapper, its fine. Thanks for adding this cleanup playbook :). Such a pain to identify and delete all resources manually.
