VMWare-NSXv: VMWare NSXv extensions
For Kilo, the vendor-specific code should be moved to stackforge repo,
excluding the extensions (https://review.openstack.org/#/c/134680/).
This patch adds the extensions VMWare NSXv plugin from
stackforge/vmware-nsx repo.
There are 2 new extensions:
1. advanced_service_providers - this is required to enabled the NSXv to provide
metadata support (there is no metadata agent)
2. vnic_index - the security group support for the NSXv requires the vNIC index
Currently the test assumes delete_ports_by_device_id deletes ports in
the order they were created but nothing ensures it. This change
updates _test_delete_ports_by_device_id_second_call_failure to avoid
such (incorrect) assumption. The assumption is in general broken in
daughter change which adds a unique constraint on Port table.

Create arping helper in ip_lib
In trying to restructure the L3 agent in to more modules, some helpers
like arping will be used by several modules. It is better to relocate
it to a common module which all of them will import and use.
Since there is only one spot which passed 'distributed=True', I chose
to break the utility in to two. Also, 'distributed' doesn't really
describe what that argument is for. So, I named the second utility
differently to indicate that it is for sending garps when proxyarp is
in use for the address on the interface.

Call on dhcp-agent DhcpLocalProcess.restart() breaks dhcp

Fixs shared networks in Arista ML2 driver
When a shared network is created, it is stored
in arista_provisioned_nets under the tenant_id of
owner of the network. Later, when a different
tenant launches an instance on the shared network,
above mentioned DB is looked to find the network
under requesting tenant's ID, and it is not found,
and hence, the request is rejected.
The fix is made such that when a network is not
found under the requesting tenant's ID, check if
this network is shared network. If yes, then
check the DB to ensure that owner tenant exists
in the DB. If yes, then this is a valid request
and do not reject it. Otherwise reject it - as an
unknown tenant or network is specified in the
request.
- Don't assume the path of mktemp command. It's /usr/bin/mktemp
for some platforms. eg. NetBSD. Also, always provide a template

- Improve a regex to ignore more comments.

Fix topic for provider security group update
Commit 8098b6bd20bb12520e438ef9125dc7b96664f712 accidentally changed

before the DHCP port was created, the VM would never get its allow
rule to communicate with the DHCP server.

Speed up initial L3 full sync time
When a L3 agent starts up the initial full sync occurs
on the first periodic task interval.
This means that from the point the agent is ready to
process updates it can take ~1 minute until traffic
can start flowing through the L3 agent's routers.
When using a highly available solution (not VRRP)
the startup delay adds around a full minute to
the minimum downtime.
This patch simply does a manual (i.e. not periodic) full
sync once the L3 agent is ready (in 'after_start' method).
The change results in a much faster sync on a new agent.
With the patch it takes several seconds until routers are
created on the new/restarted L3 agent.

Fix IPv6 Subnet Slaac Check
Currently, "is_slaac_subnet" method only checks "ipv6_address_mode".

Move non-bridge-related OVSBridge methods to BaseOVS
This patch moves several methods in OVSBridge that don't really have
anything to do with OVS bridges to BaseOVS where they are a much
better fit. Since OVSBridge inherits from BaseOVS, no modules using
ovs_lib will have to change to support this move.
Also, several module-level functions that essentially re-implement
BaseOVS.run_vsctl() are moved to BaseOVS and converted to use
run_vsctl. In order to avoid changing the API, the module-level
functions are then reimplemented by creating a BaseOVS instance and
calling the associated method.

Scope metadata rpc api using a messaging namespace
This patch does a couple of things. First it adds docstrings to the
client/server pair of the rpc interface used by the metadata service
to make calls back into the Neutron server. The docs tell you where
the other side of the interface is found in the code, and where docs
are that give more info on the rules for changing them.
The second thing done in this patch is to scope this interface using a
messaging namespace. Right now some plugins expose several interfaces
via the default namespace. This effectively means they are a single
API and should be managed with a single version stream. It's much
more managable to just treat these as separate interfaces and this
change makes that explicit and functionally true. Now when a method
is invoked, the only classes considered for handling that request will
be ones marked with the right namespace.

Provide doc string pointers for the dhcp agent rpc api
There is an rpc interface defined for the Neutron plugin to be able to
execute methods in the DHCP agent. Provide docstring pointers in the
client and server side that tells you where to find the other side of
the interface.
No namespace usage is needed here. This API is the only one exposed
via the DHCP agent, so the default namespace used now is fine.
The DhcpAgent class was updated to explicitly define the
messaging.Target(). Previously it was using the equivalent one
defined in the Manager base class. Having it specified here makes it
more obvious that this is an rpc endpoint, and also provides the
obvious place that must have the version updated if the interface is
changed.
Break out config and entry point out of l3/agent file
This is done in order to show the split between a main() and

is also moved out of the agent file.
Keep main() for the time being until we get dependent
services updated.

Correct l3-agent iptables rule for metadata proxy
2 iptables rules are defined to ensure the metadata proxy is reachable
from vms on 169.254.169.254:80:
* REDIRECT 169.254.169.254:80 packets to the router on port 9697
* ACCEPT traffic to 127.0.0.1 on port 9697
The REDIRECT rule replaces destination ip by:
* 127.0.0.1 if the packet is local,
* router ip (the one on the input interface, metadata proxy case).
So ACCEPT rule filter is not matched ... the metadata proxy is only
reachable because INPUT policy is ACCEPT.
This change removes the destination constraint in the ACCEPT rule.
Currently, the bulk create operations in ML2 are executed in
a transaction. This means all precommit and postcommit operations
for such operations are in a transaction. Postcommit operations
are expected to be executed outside of transactions as they may
communicate with a backend and introduce substantial delays. This
fix removes the postcommit operations from the transaction for
bulk create network/subnet/port operations.
