With more people using our AWS account we're seeing resources being left-behind. Implement a way to cleanup old resources while allowing to specify what resources should be kept.

So far the idea was to delete everything older than 1 week unless:

• certain tag is set (for really long term things like vpcs)
• tag specifies until when we want to preserve this resource (so devels can say I'm going to need this VM for 3 weeks)
• CI label to dispose after 24h (or sooner?)
• if possible notify the creater via email in advance

Main sources of issues:

• developers
• prow - once we add https://issues.redhat.com/browse/KATA-4078
• upstream-ci - once Wainer finishes the functional CI pipeline

Some existing projects:

• https://github.com/jckuester/awsweeper
• https://github.com/RedHatQE/cloudwash - doesn't seem scalable enough, but we might improve it
