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.

Refactor the ostweaks file to allows a more easy reuse
Add a method on the osl.Sandbox interface to allow setting
knobs on the sandbox

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.

In sandbox creation we disable IPV6 config. But this causes problem in live-restore case
where all IPV6 configs are wiped out on running container. Hence extra check has been added
take care of this issue.

- Disable ipv6 on all interface by default at sandbox creation.
Enable IPv6 per interface basis if the interface has an IPv6
address. In case sandbox has an IPv6 interface, also enable
IPv6 on loopback interface.

This fix tries to fix logrus formatting by removing `f` from
`logrus.[Error|Warn|Debug|Fatal|Panic|Info]f` when formatting string
is not present.
Also fix import name to use original project name 'logrus' instead of
'log'

If xfrm modules cannot be loaded:
- Create netlink.Handle only for ROUTE socket
- Reject local join on overlay secure network
Signed-off-by: Alessandro Boch <aboch@docker.com>
Add support for overlay networking in older kernels.
Following were done to achieve this:
+ Create the vxlan network in host namespace.
+ This may create conflicts with other private
networks so check for conflicts and fail a
join if there is any conflict.
+ Add iptable based filtering to only allow
subnet bridges in the same network to forward
traffic while different network bridges will
not be able to forward b/w each other. Also
block traffic to overlay network originating
from the host itself.

This way we won't vendor test related functions in docker anymore.
It also moves netns related functions to a new ns package to be able to
call the ns init function in tests. I think this also helps with the
overall package isolation.

Make sure to always explicitly set namespace for all
kernel bound network operations irrespective of whether
the operation is performed in init namespace or a user
defined namespace. This already happens for user defined
netns. But doesn't happen for initial netns that libnetwork
runs in.

- 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
