The zebra daemon introduces the logical router initialisation.
Because right now, the usage of logical router and vrf NETNS is
exclusive, then the logical router and VRF are initialised accordingly.

upon zebra initialisation, and upon further netnamespace creation, the
the netnamespaces are created and a vrf associated to the netnamespace
is created. By convention, the name of the netns will be the same as the
VRF.
Add a stub routine that returns a fake ns identifier, in case netlink (
linux machines) is not available.
Also, upon each newly discovered NETNS, a NSID id being generated,
either by relying on kernel NSID feature, or by generating locally the
NSID ( see previous commit for more information).
