Correctly inherit __table_args__ from parent class

Where unique constraints are added to certain tables by populating
__table_args__, we need to ensure we inherit the top level
__table_args__ that define the default storage engine to use when
creating tables.

Fixes: bug 1288358
Fix _validate_mac_address method

The method _validate_mac_address previously used: netaddr.EUI(data)
which would convert data passed in to the correct mac_address representation.
For example if data=123 it would return: EUI('00-00-00-00-00-7B'). To fix
this issue I used netaddr.valid_mac() instead which returns a bool if a mac is
valid or not and does not raise. Note this file needs some improvements to
improve how exception handling is done that will come later.

Use different name for the same constraint

In DB2, a constraint-name must not identify a constraint
that was already specified within the same CREATE TABLE
statement. The current CREATE TABLE statement uses the same
constraint name 'ipv6_modes' for both ipv6_ra_mode and
ipv6_address_mode column. This change tries to use different
names.

De-duplicate unit tests for ports in Big Switch

This eliminates the separate classes that existed
for the VIF type testing. Each class was going
through all of the port tests when none of the
logic those tests were exercising was affected by
the VIF types.

This cut the number of tests run in test_restproxy_plugin
by close to 44% without a reduction in code coverage.

Cisco VPN driver correct reporting for admin state chg

Depends on reference implementation change (81124 review) that will pass VPN
service admin up/down changes to the service driver (for subsequent passing
to the device driver).

This change will save the runtime state of the IPSec connections that have
been removed due to a VPN service down change, so that this can be reported
to the plugin properly. Otherwise, without the change, there is no info
on the downed connection and no change report so the plugin thinks the
connection is still active.

In addition, the status for the VPN service will reflect whether there are
any IPSec connections ACTIVE. If one or more are acive, the service will
be active, otherwise it will be DOWN.

Updated UT to add tests for admin state and status reporting. Also changed
some IPSec create UTs because they were not cleaning up correctly upon test
failures (only seen with a live CSR).

In the future, when the Cisco CSR REST API supports admin up/down support,
the IPSec connections will not be deleted, but instead will be shut down, in
response to an admin down event (and then brought up, for admin up). During
the down time, the state will be reported correctly and no run-time state
recording needed.

ML2 Cisco Nexus MD: Support portchannel interfaces

Port of port-channel interface support that was implemented for the cisco
core plugin - https://review.openstack.org/#/c/42037

Note that additional port-channel UT already existed. (Created during
initial cisco core nexus subplugin -> ml2 cisco nexus md port.)

Deals with fails in update_*_postcommit ops

It makes all mechanism drivers called even when one
of the mechanism drivers fails during a post commit
operation for updating network/subnet/port. This is
a stopgap measure until a more comprehensive approach
is adopted and implemented.

OFA agent: use hexadecimal IP address in tunnel port name

The remote IP address is used to form the tunnel port name
With some OVS/Linux combinations there is a 15 character limit
on port names, so a name like 'gre-192.168.10.10' does not work.
This fix uses the shorter hexadecimal representation of
the IP address instead.
This problem was reported and fixed for OVS agent.

Permit ICMPv6 RAs only from known routers

Currently ingress ICMPv6 RAs are permitted from any IPs by
default to allow VMs to accept ICMPv6 RA from provider network.
In this way, VM can accept RAs from attacker VM and configure
a network prefix specified by the attacher VM.

Remove permitting ICMPv6 RAs from any IPs and add security rule
to only permit ICMPv6 RA from:

1. If the port's subnet is configured with ipv6_ra_mode value
(i.e.value is slaac, dhcpv6-stateful, or dhcpv6-stateless), RA
is sending from dnsmasq controlled by OpenStack. In this case,
allow RA from the link local address of gateway port (if the
gateway port is created).

2. If the subnet's gateway port is not managed by OpenStack, allow
the ICMPv6 RA sent from the subnet gateway IP if it's a link local
address. The administrator needs to configure the gateway IP as
link local address in this case to make the RA rule work.

fixes broken neutron-netns-cleanup

Some configuration parameters used in neutron.agent.linux.utils
were missing. The namespace attribute in the FakeNetwork object
was missing, and used in neutron.agent.linux.dhcp. Also, the
plugin object was missing for release_dhcp_port operation.

We provide a fake plugin object to accept current and any future
plugin calls as this is meant to be an standalone tool that
should work without any RPC connectivity.

FakeNetwork was switched for neutron.agent.linux.dhcp.NetModel
to follow any future changes in NetModel.

Two wrong called_once_with_args calls without assert were fixed.
