add ability to import data sources

[jgangemi]

it's not possible to access a file in a git repository that is comprised of other files in the repo.

  version = 1
}

## data

data env version {
  key     = "CI_PIPELINE_VERSION"
  default = ""
}

data git cicd {
  url   = "..."
  tag   = data.env.version.value
  files = [
    "python/togomak/build.hcl", "python/togomak/docs.hcl", "python/togomak/publish.hcl"
  ]
}

## macros

macro build {
  files = {
    "build.hcl" : data.git.cicd.files["python/togomak/build.hcl"]
  }
}

macro docs {
  files = {
    "docs.hcl" : data.git.cicd.files["python/togomak/docs.hcl"]
  }
}

macro deploy {
  files = {
    "publish.hcl" : data.git.cicd.files["python/togomak/publish.hcl"]
  }
}

## stages

stage build {
  use {
    macro = macro.build
  }
}

stage docs {
  use {
    macro = macro.docs
  }
}

stage deploy {
  use {
    macro = macro.deploy
  }
}

i'd like to condense most of this into a single hcl file store in a separate repository that can then be imported as a data source by the caller. there needs to be a way for the imported file to be able to access the other files it imports.

It is now possible to import other terraform files from git repositories using pipeline.path, which expands to the path of the togomak ci file, that means that, you can now do something like "${dirname(pipeline.path)}/somefolder/somepath.hcl" to get relative path, and so on. Let me know if that solves the issue.

Possibly covered by this as well #35

Closing this as done.
