Tags depreciation warning message in resource aws_autoscaling_group

[ymitsos]

Describe the bug
Seems the latest AWS provider deprecates usage of "tags" in favour of "tag" in Resource: aws_autoscaling_group. It is also mentioned in the official documentation (https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/autoscaling_group#tags).

To Reproduce
Using the consul-cluster module with TF >= 0.12 returns, in a deterministic way, a warning message about the depreciation of the "tags" attribute.

Expected behavior
The "tag" attribute shall be used instead.
