With this change, all the auto-detection of the addresses are removed
from libnetwork and the caller takes the responsibilty to have a proper
advertise-addr in various scenarios (including externally facing public
advertise-addr with an internal facing private listen-addr)

Ingress load balancer is achieved via a service sandbox which acts as
the proxy to translate incoming node port requests and mapping that to a
service entry. Once the right service is identified, the same internal
loadbalancer implementation is used to load balance to the right backend
instance.

This PR adds support for loadbalancing across a group of endpoints that
share the same service configuration as passed in by
`OptionService`. The loadbalancer is implemented using ipvs with just
round robin scheduling supported for now.

Add a notion of service in libnetwork so that a group of endpoints
which form a service can be treated as such so that service level
features can be added on top. Initially as part of this PR the support
to assign a name to the said service is added which results in DNS
queries to the service name to return all the IPs of the backing
endpoints so that DNS RR behavior on the service name can be achieved.

libnetwork agent mode is a mode where libnetwork can act as a local
agent for network and discovery plumbing alone while the state
management is done elsewhere. This completes the support for making
libnetwork and its associated drivers to be completely independent of a
k/v store(if needed) and work purely based on the state information
passed along by some some external controller or manager. This does not
mean that libnetwork support for decentralized state management via a
k/v store is removed.
