0.5.2 - Fix mlx5 driver spamming syslog when no SFP present

[FIX] Do not try to gather information about the SFP when there's no SFP inserted.

The mlx5 kernel driver (and possibly others) emit an error when you try to run ethtool -m <interface> on an interface that does not have an SFP inserted. We therefore newly detect when there's no SFP and do not try to gather the SFP information in this case.

0.5.1 - Fix issue #8

This release fixes issue #8 - empty values break parsing ethtool SFP information gathering.

Code refactor & python 3.9

• Code refactored to be more readable
• Added python 3.9 functionality
• Fixed a bug in detecting line speed - KBit/s and GBit/s were parsed incorrectly
• Python 3.9 or newer is now a requirement. If you run an older version of Python, please use version 0.4.4 or any older one.

0.4.4: Merge pull request #5 from cagnulein/master

bugfix: fix a bug when an interface alarm is raised. Thanks @cagnulein !

A bugfix for the previous bugfix

bugfix: The label names now don't contain forbidden characters also in names, not only in whitelist.

Bugfix for label names

Transceiver metrics initial support

• Adds support for transceiver metrics (ethtool -m <device>)
• Adds an Info metric for basic stats (ethtool <device>)
• Adds alarms if any of the transceiver metrics is above or below threshold. This metric doesn't exist if everything is within limits.

Alarms are untested as of yet. If you have an ethtool -m output for a device that shows an alarm, please create an issue and paste it there.
