checkov directory switch not repeatable

Created by: snackwagon

Describe the bug When running checkov -h, the directory switch claims it is repeatable but when you repeat it, only the last directory listed is scanned

  -d DIRECTORY, --directory DIRECTORY
                        Terraform root directory (can not be used together with --file). Can be repeated

To Reproduce Steps to reproduce the behavior:

1. Create two directories (directory1, directory2) containing valid terraform files
2. Run cli command checkov -d ./directory1 -d ./directory2
3. Only directory2 is scanned

Expected behavior Both directory1 and directory2 are scanned

Desktop (please complete the following information):

• Checkov Version: 1.0.180

Additional context I would actually prefer a recursive switch, using the -d directive multiple times is a workaround
