Add support to add/delete neighbor entries to
the sandbox. Both L3 and L2(fdb) neighbor table additions
are supported.

Added support to add a bridge the same way as any other
interface into the namespace. The only difference is linux
does not support creating the bridge in one namespace and
moving it into another namespace. So for a bridge the sandbox
code also does the creation of the bridge inside the sandbox.
Also added an optional argument to interface which can now
select one of the already existing interfaces as it's master.
For this option to succeed the master interface should be of type
bridge.

Currently sandbox code exposes bare structs
externally to the package. It is untenable
to continue this way and it becomes too
inflexible to use it to store internal state.
Changed all of them to use interfaces.
Also cleaned up a lot of boiler plate code
which needs to set into namespace.
