Scaling Policy ASG Autodiscovery

[jkrusic19]

Is your feature request related to a problem? Please describe. Hello, I was curious for the scaling policies if we could allow for AWS ASG discovery based off resource tags? Similar to what cluster-autoscaler does for AWS EKS, which we do not need to set a specific autoscaling name, it just queries tags on the resource and then pulls in the autoscaling groups.

Describe the solution you'd like. In the documentation for the ProviderConfig you specify the asg-name, instead of using a static asg-name, have users to tag=[tag id] for chemtrail to query upon. This way as new autoscaling groups get added it dynamically gets added to chemtrail to manage. This also allows for different scaling policies based on tagged resources on how it gets controlled dynamically.

Describe alternatives you've considered. Alternative, build a custom autoscaling binary/docker image.

Explain any additional use-cases. No additional use-cases I can for-see currently as this is a specific purpose.
