Conditionally enable SSM Default Host Management Configuration (#71)
* By default, AWS Systems Manager doesn't have permission to perform actions on your instances. * Default Host Management Configuration allows Systems Manager to manage your Amazon EC2 instances automatically. * After you've turned on this setting, all instances using Instance Metadata Service Version 2 (IMDSv2) in the AWS Region and AWS account with SSM Agent version 3.2.582.0 or later installed automatically become managed instances. Benefits of managed instances include the following: * Connect to your instances securely using Session Manager. * Perform automated patch scans using Patch Manager. * View detailed information about your instances using Systems Manager Inventory. * Track and manage instances using Fleet Manager. * Keep the SSM Agent up to date automatically.
