Inventory plugin for Packet host

Hello,

I am now looking on dynamic inventory script for the Packet host (https://packet.net).

I noticed there is a PR:
https://github.com/ansible/ansible/pull/17820

I treid to do some review.

I would really like to see this pushed, could some maintainer please look at it? I am very keen to help, even re-submit the PR.

Cheers,
Tomas
