batinfo not in docker image (and in requirements files...) ?

[khaffner]

Describe the bug
batinfo seems to not be in docker image. I have a laptop (Thinkpad T570) with 3 batteries, including the wireless mouse. batinfo and UPower can show all the information about these batteries, and I'd like them to show up in Glances.

To Reproduce
Steps to reproduce the behavior:

1. docker run -it nicolargo/glances python
2. >>> import batinfo
3. "ModuleNotFoundError: No module named 'batinfo'"

Expected behavior
Looking at the code (I'm not too familiar with python though), a missing batinfo seems to be expected in non-linux environments. But this environment (allthough docker) is Linux.

Screenshots
I believe I got something working interactively using batinfo

Desktop (please complete the following information):

• OS: (Docker 20.10.8 on) Pop OS 20.04 (based on Ubuntu)
• Glances Version [Glances v3.1.6.2 with PsUtil v5.8.0]
• Glances logs file:
  root@57662d45c772:/glances# tail -10 /tmp/glances-root.log
  2021-08-08 16:41:05,583 -- INFO -- Start Glances 3.1.6.2
  2021-08-08 16:41:05,583 -- INFO -- CPython 3.9.4 and psutil 5.8.0 detected
• Glances test [output of glances --issue] (only available with Glances 3.1.7 or higher)

Additional context
I also tried to create a new image based on the latest tag, and just added RUN pip install batinfo. That did not solve the issue, and I do not know what to try next.

The issue came from the fact that the batinfo dep was not in the optional-requirements.txt file (do not remember why...).

I just add it.

So the the problem will be solve when Glances 3.2.3 will be release.
