Gregory Thiemonge b3f59eeb73 Disable conntrack for TCP flows in the amphora

conntrack is used in the amphora for LVS-based listeners (UDP and
SCTP) and it's enabled by default.
Add nft/iptable rules to disable conntrack for TCP flows, it reduces
memory usage and prevents getting "nf_conntrack: table full, dropping
packet" messages.

     Disable conntrack for TCP flows in the Amphora, it reduces memory usage for
     HAProxy-based listeners and prevents some kernel warnings about dropped
     packets.
