provider/aws: Add aws_alb_listener data source (#10181)
Browse files Browse the repository at this point in the history 
* provider/aws: Add aws_alb_listener data source

This adds the aws_alb_listener data source to get information on an AWS
Application Load Balancer listener.

The schema is slightly modified (only option-wise, attributes are the
same) and we use the aws_alb_listener resource read function to get the
data.

Note that the HTTPS test here may fail due until
#10180 is merged.

* provider/aws: Add aws_alb_listener data source docs

Now documented.
