This fix the issue when sync it disable and network
is not flat we skip the binding of the normal port.

This patch update the logic to always bind normal ports
for IB physnet

Changed the way the method check the updated port such that it will
check for extra opts then the mac, if any of the two conditions is
not met, the updated port get generated again

Changed the get_vf_device_type way of getting the type of pf netdevices
by using sysfs to read the driver name instead of relying on the PCI device
ID.

This change modifies `enable_multi_interface_driver_cache_maintenance`
config opt default to True for the obvious reason that we rather have
this enabled by default than having to specify this in a config opt.

NetworkCache get() method, in case of a cache miss called
put() method with the newly fetched network object via rpc.

Since SafeNetworkCache simply wrapped the calls with a rw lock,
it caused a dead lock in case of a cache miss since a get operation
would also put.

Proposed fix is to split the get and put logic of NetworkCache.get
into two and re-implement get in SafeNetworkCache.

Unit-test which uses a real lock in case of cache miss was
added.

To support L3 (DHCP, Routing, Floating Ip) services
over Infiniband fabric, it is required that the L2
driver to support binding of normal ports.

- Internal ports only: router(non-dvr), dhcp, floating ip
- Add configuration option to enable this functionality
- Add configuration option that defines a list of physnets
  to perform the binding for normal ports. This is intended
  to allow co-existance of both eth and ib fabrics when one
  would like to use the sdn mechanism driver to configure VLANs
  for switches on one physnet but doesnt want normal ports
  to be binded to this mechanism driver.

This commits adds a new interface driver: MultiInterfaceDriver
which is a per-physnet interface driver.
The driver delegates operations to other drivers on a per-physnet
basis.

- new multi interface driver : MultiInterfaceDriver
- utilization of the network_cache module in the driver
- Configuration option for performing periodic cache maintenance
  which removes stale entries from cache
- Configuration option for providing <physnet:interface_driver> mapping
- expose MultiInterfaceDriver as 'multi' entry point

This commit adds a new module that provides caching functionality
for:

1. General objects
2. Network objects

The network cache module will be used by MultiInterfaceDriver
that will be introduced in the next commit.

Add IPoIB interface driver to be used for [un]plugging ipoib
interface.

- Add IPoIBInterfaceDriver
- extend ip_lib to allow creating/deleting ipoib device
- add configuration option that determines the IPoIB root device
  the root device will be used when creating ipoib interfaces on top
  of it.

NOTE: the driver depends on the following neutron changes:
