Introduce "com.docker.network.bridge.inhibit_ipv4" option to the bridge
network driver. If set, this option will prevent docker from setting or
modifying Layer-3 (IP) configuration on the bridge interface in any way.
This option should allow connecting containers to pre-existing network
segments (with e.g., pre-existing default gateways) while simultaneously
preserving our ability to communicate with the host and/or configure the
properties of the host-side container virtual network interface (e.g.,
delay/loss/jitter via netem), which can not be done using macvlan.

- Fix npe in sbJoin error path
- Fail again endpoint Join in case of failure
in programming the external connectivity
- In bridge, look for parent and child container configs
in the generic data
- iptables.Exists() might be called before any other call to
iptables.raw(). We need to call checkInit() then.
