Describe the Feature

When running a command like

atmos describe stacks --components=vpc 

I want to see stacks which refer to the vpc component by deriving from it. For example, if I have

components:
  terraform:
    vpc-ipv6:
      metadata:
        component: vpc
      vars: {}

I want to see that in the output.

Use Case

Similar to #141, I want to know what stacks are using a component, for example to update them when I make a breaking change to the component.
