provide cleanup guidance

[rogerthatdev]

Proposal

We should provide cleanup guidance to delete all google cloud resources deployed when deploying Emblem. This should be a bash script provided alongside setup.sh

Problems this will solve

This will help:

• Emblem developers cleanup resources when re-using a Google Cloud project
• Allow us to create testing of setup using one consistent Google Cloud project
• Ensure users are able to cleanup resources that they may be billed for.

Alternatives

At minumum we should provide users with a step by step guide to cleaning up Emblem.

cleanup.sh might be a good starting point.
