provider/aws: Add aws_alb_listener data source (#10181)

* 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
hashicorp/terraform#10180 is merged.

* provider/aws: Add aws_alb_listener data source docs

Now documented.

Provides an Application Load Balancer Listener data source.

# aws\_alb\_listener
Provides information about an Application Load Balancer Listener.
This data source can prove useful when a module accepts an ALB Listener as an
input variable and needs to know the ALB it is attached to, or other
information specific to the listener in question.
## Example Usage
```
variable "listener_arn" {
type = "string"
}
data "aws_alb_listener" "listener" {
arn = "${var.listener_arn}"
}
```
## Argument Reference
The following arguments are supported:
* `arn` - (Required) The ARN of the listener.
## Attributes Reference
See the [ALB Listener Resource](/docs/providers/aws/r/alb_listener.html) for details
on the returned attributes - they are identical.
