support for python2

[thatsk]

Looks like this plugin is only compatible with python3 but most of systems are on python2 so can we convert into python2

Python 2 is end of life come January 1st. https://pythonclock.org/?1 I don't think it makes a lot of sense to spend a bunch of time validating it on legacy Python.

If you still desire using this on system that doesn't have Python 3 you can run it inside a Docker container as part of your monitoring. Here is an example

$ cat Dockerfile
FROM python:3
RUN pip install check_docker
ENTRYPOINT [ "check_docker" ]

$ docker build .
