Mock agent RPC for FWaaS tests to delete DB objs
This changes the firewall service unit tests to
mock the RPC calls from the firewall service to
the agent. This allows the tests to fake the
agent response RPC that removes the firewall
from the DB so the all of the other objects that
the firewall depends on can be deleted.

Change report_interval from 4 to 30, agent_down_time from 9 to 75
report_interval is how often an agent sends out a heartbeat to the
service. The Neutron service responds to these 'report_state' RPC
messages by updating the agent's heartbeat DB record.
The last heartbeat is then compared to the configured
agent_down_time to determine if the agent is up or down.
The agent's status is used when scheduling networks on DHCP
and L3 agents.
In the spirit of sane defaults suited for production, these values
should be bumped to reduce the load on the Neutron service
dramatically, freeing up CPU time to perform intensive operations.

Calculate stateless IPv6 address
In order to support stateless IPv6, neutron should calculate IPv6 address base

Create new IPv6 attributes for Subnets
* Introduces two new optional attributes for Subnets:
* ipv6_ra_mode
* ipv6_address_mode
Both attributes accept the following values:
* dhcpv6-stateful
* dhcpv6-stateless
* slaac
In addition to these values, additional behaviors are specified for
when only one of the attributes is set. For example, a Neutron network
that uses a physical router as a gateway, that transmits ICMPv6 Router
Advertisement packets to configure hosts on the network will create
Neutron Subnets that have ipv6_ra_mode *not* set, and ipv6_address_mode
set to 'slaac' so that Neutron will calculate EUI64 addresses for
each port assigned to the subnet, and not spawn a Dnsmasq process.
These attributes maintain backwards compatability with the enable_dhcp
Subnet attribute, by requiring a subnet with these attributes to also
have enable_dhcp set to True.

NSX: Ensure gateway devices are usable after upgrade
The gateway device database migration upon an upgrade creates
gateway devices objects from references in network gateway
objects.
While these gateway devices are perfectly usable
in network gateways, they are not directly visible to tenants
and also cannot be updated to change details such as name,
connector type or ip as well as the client certificate.
This patch fixes the DB migration in order to ensure tenant
have access to gateway devices created after an upgrade.
This patch also modifies the l2 gateway nsxlib module to
ensure request bodies are correctly created even when not all
the attributes of a gateway device are specified.

Avoid long transaction in plugin.delete_ports()
db_plugin.delete_ports() called plugin.delete_port() under
a transaction. It leads to long transaction if plugin.delete_port
talks with external systems. This commit changes each delete_port
outside of a transaction to avoid longer transaction.
plugin.delete_ports is now called by release_dhcp_ports and
dhcp-agent ports can be deleted separately, so this changes
does not break the existing behavior.
delete_ports is renamed to delete_ports_by_device_id
to clarify the usage of this method.
NEC plugin already has this change and it is no longer needed.
_do_side_effect helper method in test_db_plugin is renamed
to more self-descriptive name.
The workflow of creating a firewall when a router without any i/f is present in that tenant
causes a KeyError on the FWAgent. The issue occurs as such routers are present in the list of
routers returned by get_routers() but are not populated in the router_info dict. Adding a check
before accessing the dict to prevent the exception. When an i/f is added to such routers -
_router_added processing in the l3agent will populate the router_info dict and the FWAgent
also picks this up in that context.

Notify nova when ports are ready
The following patch adds a callback from neutron to nova that notifies nova
when a port for an instance is *ready to be used*. After nova receives this
event it will then start the instance in a hope that when it comes up
its networking should be in working order.
NOTE: *ready to be used* currently means that a plugin changes the status
in the db associated with a port from:
NO_VALUE/PORT_STATUS_DOWN/PORT_STATUS_ACTIVE to ACTIVE/ERROR.
Neutron will then signal nova: network_vif_plugged:<status> where status
will either be 'completed' or 'failed' given the neutron port status.
Neutron also notifies nova when a port goes from status:
PORT_STATUS_ACTIVE to PORT_STATUS_DOWN and sends nova a network_vif_unplugged
event.
Currently this patch breaks multiregion support (i.e previously you could
back multiple nova regions by one neutron server) though now since neutron
needs to notify nova we'll need to add a way to determine which region a
given port is in.
For now the work around for this would be to set: notify_nova_port_active=False
in neutron to prevent neutron from sending the notification and setting:
vif_plugging_is_fatal=False in nova.conf. Doing this will keep the current
interaction where an instance will be booted without waiting for the network
to be ready.
Kill 'Skipping unknown group key: firewall_driver' log trace
This is done by trying to import the option first. If this
does not work, emit a warning instead as in most cases this is
harmless for a number of reasons: a) the service might not
even need the opt; b) if things do break down the line, we'll
see bigger traces; c) it's not gonna be long for this legacy
quantum/neutron stuff to be removed altogether.
