Description

Add the capability to generate atlantis.tf config files with custom project names using the value of the terragrunt locals variable atlantis_project_name (useful for atlantis -p flag).

Requires the terragrunt-atlantis-config --create-project-name flag.

example:

locals {
  project_name = basename(get_terragrunt_dir())
  environment  = basename(dirname(get_terragrunt_dir()))

  # Atlantis setup
  atlantis_project_name = "${local.project_name}-${local.environment}"
}

Need some help on this build issue in TestNotIgnoringParentTerragrunt.
I tried fixing it with a change on test_examples/with_parent/child/terragrunt.hcl. I'm able to pass the tests successfully when using go 1.1.8 and 1.19 though.
Not being a Golang expert, I don't really get why there is a discrepancy between expected and actual on this test.
This test failure seems to impact other PRs too, including my 2nd one.
