-# Hook execution boilerplate logic which is common to hooks, that run
-# on per dir basis. Little bit extended than `common::per_dir_hook`
-# 1. Because hook runs on whole dir, reduce file paths to uniq dir paths
-# (unique) 1.1. Collect paths to *.tfvars files in a separate variable
-# 2. Run for each dir `per_dir_hook_unique_part`, on all paths
-# (unique) 2.1. Run `terraform fmt` on each *.tfvars file
-# 2.2. If at least 1 check failed - change exit code to non-zero
-# 3. Complete hook execution and return exit code
-# Arguments:
-#   args (string with array) arguments that configure wrapped tool behavior
-#   files (array) filenames to check
