Lowercase OVS sample config section headers
The "Sample Configurations" section of ovs_neutron_plugin.ini
has uppercased section headers. In Havana the section headers
were normalized to lowercase, but the sample configs were never
updated.
This patch introduces DB mappings between neutron network and NSX
logical switches, thus not requiring anymore the Neutron network
ID to be equal to the NSX one.
This change is necessary for enabling asynchronous operations in
the NSX plugin.
This patch also performs NVP/NSX renaming where appropriate.

Raise an error from ovs_lib list operations
Previously list operations in ovs_lib returns an empty list
if RuntimeError occurs and a caller cannot distinguish an error
from normal results. This commit changes ovs_lib list operations
(get_vif_port_set, get_vif_ports, get_bridges) to raise an
exception when RuntimeError occurs.
Note: callers of these commands are ovs/nec/ryu-agent and ovs_cleanup.
- plugin agents: these commands are inside in try/except clause
in daemon loop and there is no need to change.
- ovs_cleanup: there is no error catch logic in main() at now
and it calls commands other than ovs_lib, so it can be cleanup
later if required.
It also fixes the code to use excutils.save_and_reraise_exception
when reraising an exception.
Add migration support from agent to NSX dhcp/metadata services
This is feature patch (3 of 3) that introduces support for
transitioning existing NSX-based deployments from the agent
based model of providing dhcp and metadata proxy services
to the new agentless based mode. In 'combined' mode, existing
networks will still be served by the existing infrastructure,
whereas new networks will be served by the new infrastructure.
Networks may be migrated to the model using a new CLI tool
provided, called 'neutron-nsx-manage'. Currently the tool
provides two admin-only commands:
neutron-nsx-manage net-report <net-id-or-name>
This will check that the network can be migrated and returns
the resources currently in use. And:
neutron-nsx-manage net-migrate <net-id-or-name>
This will move the network over the new model and deallocate
resources from the agent. Once a network has been migrated
there is no turning back.
The NSX plugin does not allow to reassociate a floating IP to
a different internal IP address on the same port where it's
currently associated.
This patch fixes this behaviour and adds a unit test to ensure
re-association on the same port with a different IP is possible.
A few tweaks to the unit test aux functions were necessary to
accomodate the newly introduced unit test.

This patch adds new WSGI middlewares "request_id" and "catch_errors".

Currently updates to security group rules or membership
are handled by immediately triggering a call to refresh_firewall.
This call is quite expensive, and it is often executed with a
very high frequency.
With this patch, the notification handler simply adds devices for
which the firewall should be refreshed to a set, which will then
be processed in another routine. The latter is supposed to
be called in the main agent loop.
This patch for 'provider updates' simply sets a flag for refreshing
the firewall for all devices.
In order to avoid breaking other agents leveraging the security
group RPC mixin, the reactive behaviour is still available, and is
still the default way of handling security group updates.

Fix passing keystone token to neutronclient instance

Add an explicit tox job for functional tests
This change is in support of adding a new jenkins job dedicated
to functional testing. Functional tests will no longer be
run as part of the unit tests.
In the majority of cases a port_update notification pertains
a change in the properties affecting port filter, and does
not affect port wiring, ie: the local vlan tag.
This patch simply avoids doing port wiring/unwiring if the
local vlan tag did not change.
The extra overhead for the ovs-db get operation is offset
by the fact that get commands are generally faster than
set commands, and by avoiding executing the ovs-ofctl operation.
Process port_update notifications in the main agent loop
Instead of processing a port update notification directly in
the RPC call, the actual processing is moved into the main
rpc loop, whereas the RPC call just adds the updated port
identifier to a set of updated ports.
In this way, a port_update notification won't compete with the
main rpc loop, causing long delays into its completion under
heavy load. Also, repeated port_update notifications received
within a single iteration of the main agent loop will be
coalesced and processed only once.
This will also avoid the risk of processing notifications out
of order thus ending up with an actual configuration which
differs from the desired one.
This patch still performs L2 wiring for updated ports even if
it is necessary only when the administrative state of a port
changes.
The update_ports method has been renamed to scan_ports as the latter
name appears to be more in line with what the method actually does.
