Arnaud Porterie f42348e18f Add `--userland-proxy` daemon flag 
The `--userland-proxy` daemon flag makes it possible to rely on hairpin
NAT and additional iptables routes instead of userland proxy for port
publishing and inter-container communication.

Usage of the userland proxy remains the default as hairpin NAT is
unsupported by older kernels.

Lars Kellogg-Stedman 3559b4177e fix various problems with iptables.Exists 
This modifies iptables.Exists so that it must be called with an explicit
table and chain.  This allows us (a) to generate an appropriate command
line for "iptables -C", which was not previously possible, and (b) it
allows us to limit our strings.Contains() search to just the table and
chain in question, preventing erroneous matches against unrelated rules.

Resolves #10781
