feat: introducing "copy_terraform_lock_file" to fine tune Lock File Handling

[rodrigorfk]

Description

Fixes #1653.

This PR introduces a new attribute called copy_terraform_lock_file under the terraform block as following:

terraform {
  ...
  copy_terraform_lock_file = false
}

The default value is true and does not change any existing Terragrunt behaviour, once it is defined as false, Terragrunt will stop copying the .terraform.lock.hcl file from the temporary terragrunt directory to the working directory.

hello @rodrigorfk @denis256 , hope you're doing well. Can I ask if this merge can be completed sometime soon?

my team found this merge request and we could all use this feature since we're trying to create a remote and client setup for terragrunt and versioning could become an issue if there are locks on both remote and client side.
