Support for lifecycle hooks

[vsoch]

Describe the Feature

I'd like to be able to use https://github.com/meltwater/terraform-aws-asg-dns-handler and this requires being able to specify lifecycle hooks to the autoscale group.

Expected Behavior

I can add this module, define the hooks, and generate hostnames for my autoscale groups.

Use Case

I need hostnames or predictable networking for my autoscale groups.

Describe Ideal Solution

I can add a few lines to my main.tf and this will work.

Alternatives Considered

I've been experimenting with this all yesterday and haven't gotten anything working.

Additional Context

Recipe I'm working on is here: https://github.com/converged-computing/flux-terraform-ami/pull/1/files#diff-6e45d26e502f88302f69c4c196babd8939186d9cd298f94caca283c128a2d186
