v0.59.0

Correct enabled behavior @syphernl (#147)

what

• Replaced the enabled flag with distribution_enabled
• Corrected behavior for actual enabled flag to prevent from creating any resources

why

• The enabled input was being used to manage the distribution state, which does not match the description of "Set to false to prevent the module from creating any resources" since setting enabled to false still resulted in the CloudFront distribution and S3 bucket to be created.
• The behavior is now similar to that of terraform-aws-cloudfront-cdn
