* provider/aws: Add aws_alb data source This adds the aws_alb data source for getting information on an AWS Application Load Balancer. The schema is nearly the same as the resource of the same name, with most of the resource population logic de-coupled into its own function so that they can be shared between the resource and data source. * provider/aws: aws_alb data source language revisions * Multiple/zero result error slightly updated to be a bit more specific. * Fixed relic of the copy of the resource docs (resource -> data source)
