False positive: Cyclic import in Python

**Description of the false positive**

CodeQL falsely detects a cyclic import in a Pull request.

* There is an existing cyclic import in the code which is mitigated with an import inside of a function.
> toolopts imports global variables from systeminfo inside of `_register_options()`
> systeminfo imports toolopts
* The pull request includes switching the python modules that the identifiers are being defined in and reversing the imports so that only one module has to import the other
> toolopts now implements the global variables
> toolopts no longer imports systeminfo at all
> systeminfo now imports the global variables from toolopts

* Site of the removal of import: https://github.com/oamg/convert2rhel/pull/820/files#diff-a7331917babf0a1504893963baab7ad842640877734e5dbeb39ebf97ec584565L130

**URL to the alert on GitHub code scanning (optional)**

Start with the linked convert2rhel pull request and compare the import changes in toolopts and systeminfo, especially systeminfo's import and _register_options(). Reproduce the CodeQL cyclic-import alert against the revised arrangement and confirm that the existing mitigated cycle is no longer reported.
