Using aws-terraform-cloudwatch_alarm to create the following CloudWatch Alarms:

Terraform 0.12 upgrade

Several changes were required while adding terraform 0.12 compatibility. The following changes should
made when upgrading from a previous release to version 0.12.0 or higher.

Module variables

The following module variables were updated to better meet current Rackspace style guides:

• security_group_list -> security_groups
• resource_name -> name

The following variables are no longer neccessary and were removed

• additional_ssm_bootstrap_step_count
• install_scaleft_agent

Several new variables were introduced to provide existing functionality, with a simplified format. The original formmating was also retained to allow easier transition.

New variables tags and tags_asg were added to replace the functionality of the additional_tags variable. tags allows setting tags on all resources, while tags_asg sets tags only on the ASG itself. additional_tags will continue to work as expected, but will be removed in a future release.

New variable ssm_bootstrap_list was added to allow setting the SSM association steps using objects instead of strings, allowing easier linting and formatting of these lines. The additional_ssm_bootstrap_list variable will continue to work, but will be deprecated in a future release.
