[Bug]: action='extend' in v0.2.0 breaks compatabilty with Python3 < 3.8

[log1-c]

Please try to fill out as much of the information below as you can. Thank you!

• Yes, I've searched similar issues on GitHub and didn't find any.

Which version contains the bug?

0.2.0

Describe the bug

v0.2.0 introduced the exclude parameter which is defined with action='extend' in the code.
This renders the script unusable on systems having a Python3 version lower than 3.8, like RHEL8 for example.

How to recreate the bug?

Download and execute v0.2.0 of the script on a system with Python3 lower than 3.8

Hi, while I wouldn't call this a "bug" I do understand that it is inconvenient.

Since earlier versions than Python 3.8 are end-of-life and Python 3.8 should be available in the RHEL8 repos right now, I feel a bit reluctant to change the current code.

However, shouldn't be to much of a change, so we could have version without action='extend' on a "backport" branch.

@log1-c Do you have code that is working for you?

Thanks for the quick reply.
Wasn't shure if I should open it as a "bug" or more a "documentation",as I mostly meant it as an FYI. And I can understand if you are not willing to change the code!

I have switched back to a earlier version, as we currently don't use the exclude parameter.
Will also discuss internally if raising the Python3 version is an option.

I'll update the README accordingly

This should work on older versions, I tested it on Python 3.6: https://github.com/NETWAYS/check_vmware_nsxt/tree/backport

README is updated on both branches.

@log1-c can you confirm the code is working?

[log1-c]

yes, script from https://github.com/NETWAYS/check_vmware_nsxt/tree/backport works.
thank you!
