Building upon #1 and #2, I want to make aws-checker easier to test, without the real AWS infrastructure.
As a starter, this PR adds
localstack/s3.go
to support injecting a custom S3 endpoint resolver to redirect any S3 requests to localstack's S3 endpoint. This also extracts thechecker
struct out of theRun
function, supporting injecting the resolver and making it more responsive to signals when the periodic check is still in progress.
