Terrawrap

Changed

- Updated plan check to ignore git directory

Changed

- Update `PyYAML` package to version >=5.3.1,\<6

Changed

- Check that a path is a directory before attempting to run `plan` when running `plan_check`

Changed

- Terraform provider version lock files are not automatically deleted

Changed

- Refactored `plan_check` when using `--modified-only` to build a graph when scanning for directories that
were changed or affected by a change (such as symlinks, module changes, auto.tfvars, etc). This fixes a
number of edge cases where `plan_check` missed directories that should have had `plan` run.

Changed

- Fixed a bug in `graph_apply` when there are symlinks to directories above the directory being applied
