In this PR I have implemented graceful restart of l3afd means upgrading/restarting the l3afd without affecting ebpf programs state and having same level of control on eBPF programs as we were having on old instance.

This PR is dependent on
l3af-project/eBPF-Package-Repository#92
l3af-project/l3af-arch#124

Looks pretty good to me, just a few inline questions. And make sure to modify that line that was pointed out by @sanfern

LGTM, thanks for this amazing work!

Although, next time let's try to make multiple smaller PRs, 40 files is a lot to review. ;)
