Support ALB (Application Load Balancer)

[dtan4]

WHY

Recently we migrated our CLB to ALB. We use elastic-load-balancing-tools for migration, so new ALBs have not been written as Terraform code yet.

WHAT

Support ALB code generation.

TODO

• tf
• tfstate
• subcommand (terraforming alb)

current terraform plan result:

~ aws_alb.xxx
    access_logs.#:         "0" => "1"
    access_logs.0.enabled: "" => "false"

~ aws_alb.yyy
    access_logs.#:         "0" => "1"
    access_logs.0.enabled: "" => "false"
    idle_timeout:          "300" => "60"

👌

No changes. Infrastructure is up-to-date. This means that Terraform
could not detect any differences between your configuration and
the real physical resources that exist. As a result, Terraform
doesn't need to do anything.
