Dependencies among common modules

[matejkostros]

Describe the solution you'd like
I would like to have the possibility to reference two modules in _envcommon folder through dependenc[y|ies] block.

Describe alternatives you've considered
I have considered having such dependencies on terraform module level however, this takes away the possibility to use standardized modules

Additional context
When I try to add a dependency to _envcommon like:
_envcommon/dependencies/vpc/terragrunt.hcl
And in my _envcommon/alb.hcl I state a depenency like:

dependency "vpc" {
  config_path = "${dirname(find_in_parent_folders())}/dependencies/vpc/"
}

It resolves to: /work/_envcommon/dependencies/vpc/terragrunt.hcl but fails to load env.hcl:
Call to function "find_in_parent_folders" failed: ParentFileNotFound: Could not find a env.hcl in any of the parent folders of /work/_envcommon/dependencies/vpc/terragrunt.hcl

Not sure if it's the same use case but here is how I reference my dependency:

dependency "vpc" {
  config_path = "${get_terragrunt_dir()}/../vpc"
}

I've actually figured it out on my own.
It is sufficient to just place in my _envcommon/alb.hcl following

dependency "vpc" {
  config_path = "../vpc"
}

Then just use the outputs of the dependency like:

inputs {
  vpc_id = dependency.vpc.outputs.vpc_id
}

Can we add it to a documentation README?
