Support for triggers / detect dependency changes

[dmlemos]

I'd like to be able to run a module every time a dependency module changes.

Given dummy example main.hcl

param "users" {}
param "dep_packages" {}

module "setup-x.hcl" "setup-x" {
  params = {
    app_name = "{{param `app_name`}}"
    version = "{{param `version`}}"
  }

  depends = ["module.packages"]
}

module "packages.hcl" "packages" {
  params = {
    packages = ["{{param `dep_packages`}}"]
  }
}

Module setup-x should be trigger every time dep_packages change.
