When its "property" metadata has "something"

Add Terraform's actions on the resource to the resource

Addresses #408 #426

Add the actions list on resource_changes to the respective resources as suggested by @mdesmarest

New Step

When its "property" metadata has "something"

This step filters a resource out if it has property metadata that has something value. Metadata are considered to be key, value pairs outside of values, which includes the properties of the resource.

Following is how an aws_instance example is represented in stash.

{'address': 'aws_instance.example',
 'mode': 'managed',
 'type': 'aws_instance',
 'name': 'example',
 'provider_name': 'registry.terraform.io/hashicorp/aws',
 'values': {
  'ami': 'ami-034bf895b736be04a',
  'arn': 'arn:aws:ec2:us-west-1:704778554736:instance/i-0d6a689453a806e50',
  'tags': {'Name': 'HelloWorldChange'},
  ...
  },
 'actions': ['update']
}

actions, provider_name, or address are considered to be metadata. However ami, arn, and tags are considered to be otherwise, as they are in values. The debugger could be used to see the metadata present at a given step.

When its "property" metadata does not have "something"

Works the same way but other way around. Note that not having "property" metadata will also let the resource pass.

Future directions

• make it so that metadata like actions don't disappear during then steps
• Then steps for metadata
• More when steps (one without value and only key)
• Ability to modify any step so that it uses/excludes whichever the data you would like:
  • values
  • metadata
• regex / generalized regex

Adding module tests inflated the code quite a lot
