autoplan not working for .hcl files with default auto plan

[JoshiiSinfield]

Hi,

I'm seeing an issue where autoplan is not detecting changes in a directory where terragrunt.hcl file is updated.

I'm using the "latest" version of the docker container..

We have repos.yaml setup with the following:

---
repos:
  - id: /.*/
    allow_custom_workflows: true
    allowed_overrides:
      - workflow
    apply_requirements: [approved, mergeable]
    workflow: terragrunt


# workflows lists server-side custom workflows
workflows:
  terraform:
    plan:
      steps:
        - init
        - plan
    apply:
      steps:
        - run: echo Running Terraform Apply
        - apply
  terragrunt:
    plan:
      steps:
        - run: terragrunt plan --terragrunt-non-interactive -no-color -out $PLANFILE
    apply:
      steps:
        - run: terragrunt apply --terragrunt-non-interactive -no-color $PLANFILE

  terragrunt-tf-11:
    plan:
      steps:
        - run: terragrunt-0.18.7 plan --terragrunt-non-interactive --terragrunt-tfpath /usr/local/bin/tf/versions/0.11.14/terraform -no-color -out $PLANFILE
    apply:
      steps:
        - run: terragrunt-0.18.7 apply --terragrunt-non-interactive --terragrunt-tfpath /usr/local/bin/tf/versions/0.11.14/terraform -no-color $PLANFILE

  terragrunt-all:
    plan:
      steps:
        - run: terragrunt plan-all --terragrunt-source-update --terragrunt-non-interactive -no-color -out $PLANFILE
    apply:
      steps:
        - run: terragrunt apply-all --terragrunt-source-update --terragrunt-non-interactive -no-color

the repo also has atlantis.yaml configured as below(small snippet):

- name: josh-test1
  dir: josh/test1
  workspace: josh-test1
  workflow: terragrunt-tf-11
  terraform_version: v0.11.14
- name: josh-test2-tf12
  dir: josh/test2/tf12
  workspace: josh-test2-tf12
  workflow: terragrunt

Both of these configurations work together for a new folder added, however when modifying files that already exist it doesn't pick them up by default.

I've seen #748 and have traced through code and comments and believe

atlantis/server/events/yaml/raw/autoplan.go

Line 7 in 75da89e

const DefaultAutoPlanWhenModified = "**/*.tf*"

is causing the issue. I think it should be updated to allow "**/terragrunt.hcl" too.

Output in the logs shows looping through every project configured in the atlantis.yaml, but ending with: "0 projects are to be planned based on their when_modified config".
we don't specify a when_modified anywhere as can be seen, which is what got me searching for a default and hence the above suggestion.

Cheers,
Josh

Yes this should be **/*.tf* and **/terragrunt.hcl
