NSX: drop support to deprecated dist-router extension
The NSX plugin originally implemented its own 'dist-router' extension.
During the Juno timeframe the DVR extension was introduced and the NSX
plugin was ported to support both. At the same time 'dist-router' was
marked for removal in Kilo.
Now that Kilo opened, we can drop the deprecated one.

Refactor _process_routers to handle a single router
The method _process_routers no longer handles multiple routers. The
only caller of this method would construct a list of exactly one
router in order to make the call. This made the for loop unnecessary.
The method's logic is too heavy for its current purpose. This commit
removes much of the weight.
The use of the sets in this method is also no longer necessary. It
became clear that all of it boiled down to "if the router is not
compatible with with this agent but it is known in router_info from
before then we need to remove it." This is an exceptional condition
that shouldn't be handled in this method so I raise an exception and
handle it in process_router_update where other router removal is
handled. Logging was added for this exceptional condition.
The eventlet pool was also obsolete. It was used to spawn two methods
and there was a waitall at the end. The other refactoring made it
clear that the two spawns were mutually exclusive. There was only one
thread spawned for any given invocation of the method and the eventlet
pool is overkill.

Disable PUT for IPv6 subnet attributes
In Juno we are not ready for allowing the IPv6 attributes on a subnet
to be updated after the subnet is created, because:
- The implementation for supporting updates is incomplete.
- Perceived lack of usefulness, no good use cases known yet.
- Allowing updates causes more complexity in the code.
- Have not tested that radvd, dhcp, etc. behave OK after update.
Therefore, for now, we set 'allow_put' to False for the two IPv6
attributes, ipv6_ra_mode and ipv6_address_mode. This prevents the
modes from being updated via the PUT:subnets API.
Note: There are several other unrelated unit tests that also break with a
randomized PYTHONHASHSEED, but they are not addressed here. They will be
addressed in separate patches.

The important difference between the agents is their 'host' value so
that they create different namespaces, and 'state_path' value so the
agents get their own filesystem root.

Iterate over same port_id if more than one exists
In certain cases where multiple ports can have the same
external_ids:iface_id property, the ovs agent will arbitrarily choose
one and ignore the rest. In case the chosen port isn't on the
integration bridge the ovs agent is managing, an error is returned to
the calling function. This is faulty since one of the other ports may
belong to the correct bridge and it should be chosen instead.
This is interesting for future L3 HA integration tests, where 2
different instances of l3 agents are needed to run on the same machine.
In this case, both agents will register ports which have the same
iface_id property, but obviously only one of the ports is relevant for
each agent.
