InterfaceOptions() returned an IfaceOptionSetter interface, which contained
"methods" that returned functional options. Such a construct could have made
sense if the functional options returned would (e.g.) be pre-propagated with
information from the Sandbox (network namespace), but none of that was the case.
There was only one implementation of IfaceOptionSetter (networkNamespace),
which happened to be the same as the only implementation of Sandbox, so remove
the interface as well, to help networkNamespace with its multi-personality
disorder.
This patch:
- removes Sandbox.Bridge() and makes it a regular function (WithIsBridge)
- removes Sandbox.Master() and makes it a regular function (WithMaster)
- removes Sandbox.MacAddress() and makes it a regular function (WithMACAddress)
- removes Sandbox.Address() and makes it a regular function (WithIPv4Address)
- removes Sandbox.AddressIPv6() and makes it a regular function (WithIPv6Address)
- removes Sandbox.LinkLocalAddresses() and makes it a regular function (WithLinkLocalAddresses)
- removes Sandbox.Routes() and makes it a regular function (WithRoutes)
- removes Sandbox.InterfaceOptions().
- removes the IfaceOptionSetter interface.
Note that the IfaceOption signature was changes as well to allow returning
an error. This is not currently used, but will be used for some options
in the near future, so adding that in preparation.

"Pay no attention to the implementation behind the curtain!"
There's only one implementation of the Sandbox interface, and only one implementation
of the Info interface, and they both happens to be implemented by the same type:
networkNamespace. Let's merge these interfaces.
And now that we know that there's one, and only one Info, we can drop the charade,
and relieve the Sandbox from its dual personality.

No context in the commit that added it, but PR discussion shows that
the API was mostly exploratory, and it was 8 Years go, so let's not
head in that direction :) b646784859

The method to restore a network namespace takes a collection of
interfaces to restore with the options to apply. The interface names are
structured data, tuples of (SrcName, DstPrefix) but for whatever reason
are being passed into Restore() serialized to strings. A refactor,
f0be4d126d, accidentally broke the
serialization by dropping the delimiter. Rather than fix the
serialization and leave the time-bomb for someone else to trip over,
pass the interface names as structured data.

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.

Modify the loadbalancing for east-west traffic to use direct routing
rather than NAT and update tasks to use direct service return under
linux. This avoids hiding the source address of the sender and improves
the performance in single-client/single-server tests.

New load balancing code will require ability to add aliases to
load-balncer sandboxes. So this broadens the OSL interface to allow
adding aliases to any interface, along with the facility to get the
loopback interface's name based on the OS.

When stale delete notifications are received, we still need to make sure
to purge sandbox neighbor cache because these stale deletes are most
typically out of order delete notifications and if an add for the
peermac was received before the delete of the old peermac,vtep pair then
we process that and replace the kernel state but the old neighbor state
in the sandbox cache remains. That needs to be purged when we finally
get the out of order delete notification.

- Maps 1 to 1 with container's networking stack
- It holds container's specific nw options which
before were incorrectly owned by Endpoint.
- Sandbox creation no longer coupled with Endpoint Join,
sandbox and endpoint have now separate lifecycle.
- LeaveAll naturally replaced by Sandbox.Delete
- some pkg and file renaming in order to have clear
mapping between structure name and entity ("sandbox")
- Revisited hosts and resolv.conf handling
- Removed from JoinInfo interface capability of setting hosts and resolv.conf paths
- Changed etchosts.Build() to first write the search domains and then the nameservers
