L3 Agent restart causes network outage

When a L3 agent controlling multiple qrouter namespaces
restarts, it destroys all qrouter namespaces even if
some of them are still in use.  As a result, network
traffic could be stopped on the VMs that use the
networks associated with these namespaces.

So what is needed is for the L3 agent to preserve those
qrouter namespaces a L3 agent instance recognizes and to
destroy those it does not know about.

Fix ValueError in ip_lib.IpRouteCommand.get_gateway()

As metric is not necessarily the 5th word of the gateway line, the
method should search the string 'metric' in the line and pick the next
word as the metric value.

Fix request timeout errors during calls to NSX controller

Sometimes two correlated exception traces are observed in
the server log for the Neutron Server backed by NSX:
RequestTimeout (The nsx request has timed out) and
OperationalError (Lock wait timeout exceeded). This is
generally described by Guru Salvatore Orlando as the,
and I quote, the "infamous eventlet-mysql deadlock".

This patch tries to address the issue by adding a
cooperative yield in the nsx client code (it’s a good idea
to call sleep(0) occasionally in any case) and also by
avoiding the unnecessary spawning of another Greenthread
within a call that is already executed in Greenthred
itself.

Parse JSON in ovs_lib.get_vif_port_by_id

This patch replaces regex matching of text output with parsing
of JSON output in ovs_lib.get_vif_port_by_id.
This makes the code more reliable as subtle, possibly even
cosmetic, changes in ovs-vsctl output format could cause the
regular expression match to fail.

Also, this makes the code consistent with ovs_lib.get_vif_port_set
which already uses JSON output.

Finally this patch slightly changes the behaviour of
ovs_lib.get_vif_port_by_id returning None if elements such as
mac address or ofport were not available.
