when loxilb is enabled and started, enable the
firewall SNAT for green network so green network
could have initiate outgoing traffic like internet
access.
we can achieve this by restoring firewall SNAT setting
from default /var/ipfire/loxilb/FWconfig.txt when loxilb
start up with --config-path=/var/ipfire/loxilb thanks
to the enhancement addressed in issue:

When loxilb and keepalived are enabled, after BPFire
rebooted, loxilb and keepalived failed to start and
shows as "STOPPED" from UI, this is not expected since
we want to loxilb and keepalived to continue to be enabled
after reboot based on the enabled state of loxilb and
keepalived before reboot.

BPFire red0 does not support multicast, need to
have unicast peer configured, then the virtual
ipaddress can be added to red0 interface.
the UI requires /var/ipfire/keepalived/runsettings
/var/ipfire/keepalived/settings to be created, so
add them lfs/configroot

change keepalived default config to
/var/ipfire/keepalived/keepalived.conf so keepalived WebUI
could read/write the configuration file. also add
/var/ipfire/keepalived directory

keepalived: create /var/ipfire/keepalived
since we added loxilb ip management to add ip on
red0 interface, we can select the virtual ip from
red0 interface.

Re-arrange the menu to have BPF centric
main menu, this also easy the developing
of loxilb load balancer GUI since loxilb
will have multiple functions like enable
loxilb, create loxilb lb, create loxilb ip
...etc, so each loxilb function has their
own CGI UI.

XDP dns rate limit program has static tail call
which requires revert xdp-tool commit:
(039bdea "xdp-loader: Only load the BPF program we need from object files")
XDP dns rate limit program also uses bpf_printk helper which is not
supported on FireBeeOS since kernel CONFIG_BPF_EVENTS which allows user
to do kprobe, uprobe, tracepoint is not enabled, so bpf_printk helper is
not available, so removed bpf_printk

This reverts commit 7773f82726.
After ISO installation in real hardware and reboot,
the boot process appears to be "stucking" in
"dracut: Switching root".
see https://github.com/vincentmli/FireBeeOS/issues/1
revert the commit resolves the issue, I suspect maybe
the output after "dractu: Switching root" is directed
to serial console? anyway revert this change temporarily.
flash image build still need to have serial console access
for better user experience when trying flash image in KVM/Libvirt
virtual environment.
