[bird, networking] Carry forward PR 1541

[TurboTurtle]

Two commits that first add the bird plugin and second add several devlink commands to the networking plugin, originally proposed in #1541, which seems to have been abandoned.

Commits have been updated to reflect modern sos/plugin design and current state of the networking plugin.

Closes #1541

Congratulations! One of the builds has completed. 🍾

You can install the built RPMs by following these steps:

• sudo yum install -y dnf-plugins-core on RHEL 8
• sudo dnf install -y dnf-plugins-core on Fedora
• dnf copr enable packit/sosreport-sos-3763
• And now you can install the packages.

Please note that the RPMs should be used only in a testing environment.

There could be some passwords stored in the config file. Inside bird.conf we have two examples:

#		password "hello" { algorithm hmac sha256; }; # Default is MD5
#	password "secret";	# Password used for MD5 authentication

First one is for protocol RIP, second one is for BGP. The format seems to be very similar if not the same, so it should be easy to obfuscate these lines.

Also I think the user can specify a log file instead of syslog, so it may be worth to check the config file for an entry with a pattern that starts like this:

log "filename"

Interesting, the example config file I was looking at had no passwords but sure enough the upstream docs call that out.

Pushed a new set with an added postproc() and grabbing the log files called out in bird.conf.
