Add collector to get pci device data

[brett060102]

Add collection of lsmod and PCI data to the hwdata infor block

This done by adding a collector that will invoke
lspci -s .0 and lsmod

Requires adding pciutils to required package for suseconnect

The size of the additional payload in the heartbeat depends on how many pci devices are on the system and
number of modules loaded into the kernel. See:

For more information.

In a more general comment, please use goimports/gofmt. As in, your Go environment does not align at all with Go's coding conventions. This is something that should've been detected via our CI, but we never bothered to do so 😅 Hence, take a look at that, and run make check-format to ensure that your code is up to Go's coding conventions.

Thank you for "gofmt" reference. I did not know about it. Does make things easier.

By the way, does the WIP label still apply for this PR?

[brett060102]

yes, this should stay WIP for now. We don't want this to land until we know how it would effect RMT's and SCC.

Ok, then I will not review this further. Ping me again when you need another review.
