expose log bucket lifecycle settings

[deadlysyn]

what

• Allow module consumers to enable log bucket lifecycle
• Enable fine-grained control of retention/tiering
• Use defaults to maintain current behavior for those who don't opt-in

why

• terraform-aws-s3-log-storage already created lifecycle rule, but control was not bubbled up
• Supports work in terraform-aws-lb-s3-bucket to expose lifecycle settings
• Lifecycle is a standard way to manage s3 assets
• Many will have different requirements, so this provides required flexibility

references

• Use closes #39
