After moving libnetwork to this repo, we need to update all the import
paths for libnetwork to point to docker/docker/libnetwork instead of
docker/libnetwork.
This change implements that.

https://github.com/docker/libnetwork/pull/2419 and
https://github.com/docker/libnetwork/pull/2407
attempted to seperate out empty parent and internal for
macvlan and ipvlan networks
However it didnt pass the integration tests in moby
https://github.com/moby/moby/pull/40596 and exposed some
more plumbing that needed to be done to make sure
we separate the two things
If the -o parent is empty we create a dummylink
and if internal is set we dont add a default gateway
and make sure north-south communication cannot take place
(only east-west / container-container can)

Using dummy interface allows communication beween containers only if
they are running on the same node in swarm.

This commit carries forward the work done in
https://github.com/docker/libnetwork/pull/2295
and fixes two things
1. Allows macvlan and ipvlan to be restored properly
after dockerd or the system is restarted
2. Makes sure the refcount for the configOnly network
is not incremented for the above case so this network
can be deleted after all the associated ConfigFrom networks
are deleted

The previous code used string slices to limit the length of certain
fields like endpoint or sandbox IDs. This assumes that these strings
are at least as long as the slice length. Unfortunately, some sandbox
IDs can be smaller than 7 characters. This fix addresses this issue
by systematically converting format string calls that were taking
fixed-slice arguments to use a precision specifier in the string format
itself. From the golang fmt package documentation:
For strings, byte slices and byte arrays, however, precision limits
the length of the input to be formatted (not the size of the output),
truncating if necessary. Normally it is measured in runes, but for
these types when formatted with the %x or %X format it is measured
in bytes.
This nicely fits the desired behavior: it will limit the number of
runes considered for string interpolation to the precision value.

With the introduction of a driver generic gossip in libnetwork it is not
necessary for drivers to run their own gossip protocol (like what
overlay driver is doing currently) but instead rely on the gossip
instance run centrally in libnetwork. In order to achieve this, certain
enhancements to driver api are needed. This api aims to provide these
enhancements.
The new api provides a way for drivers to register interest on table
names of their choice by returning a list of table names of interest as
a response to CreateNetwork. By doing that they will get notified if a
CRUD operation happened on the tables of their interest, via the newly
added EventNotify call.
Drivers themselves can add entries to any table during a Join call by
invoking AddTableEntry method any number of times during the Join
call. These entries lifetime is the same as the endpoint itself. As soon
as the container leaves the endpoint, those entries added by driver
during that endpoint's Join call will be automatically removed by
libnetwork. This action may trigger notification of such deletion to all
driver instances in the cluster who have registered interest in that
table's notification.
