Updated README, added --retain-traffic-data to cluster-destroy

[chelma]

Description

• A couple quick fixes per user feedback.
• The new --retain-traffic-data flag works the same way as the old default behavior of cluster-destroy; I just added a check that they provided either that flag or --destroy-everything to make the choice explicit and obvious.

Tasks

• Some updates per User Feedback #158

Testing

• Tested the new option locally against my AWS account:
