Stop using portbindings_db in BSN ML2 driver
Avoids using the portbindings_db in the Big Switch
ML2 driver since ML2 has deprecated that database for
its own version that tracks the same information.
Also eliminates unnecessary 'binding_host' field since
it is now always the same as as the 'portbinding:host_id'
field.
A minor change is made to the Arista API between ML2 Driver and the
back-end. This fix addresses this change to align Icehouse release with
Arista EOS releases.
Second firewall creation returns 500, but it is an expected behavior
of firewall reference implementation and an internal server error
should not be returned.
Gateway certificates are validated by the NSX backend.
The code currently treats a failure in certification
validation as a backend failure and therefore returns
a 500 status code.
This patch changes this behaviour by returning a 400
status code and an appropriate error description.
To this aim a handler for 400 errors has been added to
the NSX API client.

Cancelling thread start while unit tests running
This change modifies the Radware driver and its unit testing code
to not start operations completion thread while unit tests are running.
The driver initialization changed not to start the operations completion thread,
the thread is started only when operation completion item is inserted into the queue
for the first time.
The operation completion functionality was moved to a new function which
is called by the operations completion thread run() function.
The run() function still have the functionality of popping operation completion
items out of the queue and push failed items back.
Unit testing code mocks the operation completion items queue
by calling the operations completion hanler new function when item
is added.

UT: do not hide an original error in test resource ctxtmgr
In unit tests, resource contextmanagers such as network(), subnet()
try to delete themselves after returning from yield even if an
exception occurs. However when an exception occurs, there is a case
where deletion fails. In this case original exception will be hidden
and it makes difficult to debug test failures.
Before each test starts, resources like database entries will be
recreated, so there is no need to try to delete resources even
when an exception occurs. This commit removes try-finally clause
from resource contextmanagers to make original errors visible.

Each dnsmasq instance on a network is not aware of other dnsmasq's leases.
When dnsmasq is launched with --no-hosts and is not provided an --addn-hosts
file, it can resolve only the hosts to which it gives a dhcp lease and no more.
i.e.:
If dnsmasq service n°1 gives a lease to instance n°1, and dnsmasq service n°2
gives a lease to instance n°2, both VM instances and dnsmasq services being on
the same network: instance n°1 can not resolve instance n°2, because instance
n°1 queries dnsmasq n°1, and since it did not give the lease to instance n°2,
it can not resolve it (it is not aware of its existence). Same issue if
instance n°2 tries to resolve instance n°1.
The solution is to provide dnsmasq with an --addn-hosts file of all hosts on
the network. With an --addn-hosts file, each dnsmasq instance is aware of all
the hosts on the network even if they do not give the lease for a host,
therefore each dnsmasq instance can resolve any host on their network even if
they did not provide the lease for it themselves.

Prevent cross plugging router ports from other tenants
Previously, a tenant could plug an interface into another tenant's
router if he knew their router_id by creating a port with the correct
device_id and device_owner. This patch prevents this from occuring
by preventing non-admin users from creating ports with device_owner
network:router_interface with a device_id that matches another tenants router.
In addition, it prevents one from updating a ports device_owner and device_id
so that the device_id won't match another tenants router with device_owner
being network:router_interface.
NOTE: with this change it does open up the possiblity for a tenant to discover
router_id's of another tenant's by guessing them and updating a port till
a conflict occurs. That said, randomly guessing the router id would be hard
and in theory should not matter if exposed. We also need to allow a tenant
to update the device_id on network:router_interface ports as this would be
used for by anyone using a vm as a service router. This issue will be fixed in
another patch upstream as a db migration is required but since this needs
to be backported to all stable branches this is not possible.
NOTE: The only plugins affect by this are the ones that use the l3-agent.
NOTE: **One should perform and audit of the ports that are already
attached to routers after applying this patch and remove ports
that a tenant may have cross plugged.**

Import request_id middleware bug fix from oslo
There is a bug in request-id middleware that a subsequent API request will
overwrite a request-id of a previous request when multiple API calls are
processed in parallel in request_id middleware.
This commit imports the fix in oslo.
The original version of the request_id middleware generates a request ID during
process_request() and stores the value in a variable, so it can be attached as
header in process_request(). This is pretty dangerous, since subsequent
requests will overwrite this value, and the wrong request ID may be attached to
some responses. This is particularly apparent when requests arrive in parallel.
This change replaces process_request() and process_response() with an override
of __call__(). This allows the generated req_id to be used in the response
header without needing to save it as a class-level variable.
