Add nftables table

[ilpianista]

Following the discussion in #15651, this adds the nftables table by parsing the binary output.

Tests are missing, before I write them I would like to know if this is the correct way to implement it or if I should use the cryptsetup table as reference to implement it.

hi @ilpianista 👋

Thanks for the PR! We are taking a look internally and will follow up here with next steps!

@jahzielv @zwass Just following up to see what next steps is on this.

[zwass]

I added a changes file and updated to support nft binary in multiple paths (as I found a different path when testing on Ubuntu).

Because I made changes I can't approve the PR for merging. @lukeheath or @jahzielv can you please approve?

[zwass]

Thank you @ilpianista for your contribution! This will go out in the next fleetd release.
