changes ovs agent_id init to use hostname instead of mac

In the Open vSwitch agent,
the Agent id is currently based off the mac address of the br-int.
Userspace only Open vSwitch derivatives such as Intel's DPDK
Accelerated Open vSwitch do not currently create a tap device in the kernel
to back the ovs bridges local port.
This limitation prevents reuse of the OpenVSwitch agent between both switches.

To enable reuse of the ovs agent with Intel's DPDK Accelerated Open vSwitch,
the proposal is to change the  generation of the  agent_id to use the hostname,
instead of the mac address of the br-int.

For several plugins such as the nec,mlnx,hyperv and onconvergence agents
the hostname is used to create the agent id.
Using the hostname will normalise the agent_id between these 5 neutron agents,
additionally log readability will also be improved,
if log aggregation is preformed across a cluster
as it will be easier to identify which node the log is from.

the hostname is retrived from cfg.CONF.host

Also optimize deleting logic.

Adding static routes data for members

Adding extra data on member entities for routing.
Subnet, mask and gateway data is attached to each member.
Default values are:
 subnet=255.255.255.255
 mask=255.255.255.255
 GW=255.255.255.255

Only in case when LB is connected to both, pool sub-net and vip sub-net
and member is not on pool's sub-net, routing info will be determined
instead of setting to default values:

1. In case when member's port is found, member's subnet and mask
   data will be set to those of the port, gateway will be set to pool's
   gateway address

2. In case when no port found or more than one port found for member's IP address,
   member's subnet will be set to member's IP address value , gateway will be set
   to pool's gateway value, and mask will be set to default 255.255.255.255

New unit tests were added for testing following scenarios:
1. Adding 3 members on 3 different sub-nets, vip's, pool's and other sub-net
2. Adding member on other than pool's sub-net with no port
3. Adding member on other than pool's sub-net with multiple ports with same IP address
   but on different sub-nets

Internal vip graph building function was added (_populate_vip_graph)
for more convenient code re-use and better structure

linuxbridge-agent: process port updates in the main loop

This patch changes the way the linuxbridge agent processes port update
notifications. It does the same for the lb-agent as was done for the
ovs-agent in I219c6bdf63b0b5e945b655677f9e28fa591f03cd.
Now the RPC call just adds the updated tap device name to a set of
updated devices, and the actual processing is done in the main RPC loop.
This should solve the problems were port_update RPCs were competing
with the main loop/greenthread and with each other to do the same task
- like adding a tap or interface to a bridge - which lead to races and
was inefficient. Now repeated port_update notifications received within
a single main loop iteration will be coalesced and processed only once.

and throws an exception if they are incompatible.

Pass 'top' to remove_rule so that rule matching succeeds

When deleting a vpn-site-connection, deleting the nat rule would
fail because it was created with top=True, but top defaults to
'false' in remove_rule and was not being passed. This caused the
rule matching to fail and the rule to not be deleted.

NSX sync cache: add a flag to skip item deletion

This new flag will prevent updates on single resources, which
can happen asynchronously to the main synchronization thread,
from processing the 'changed' flag for items in the cache and
delete items not present anymore in NSX.

This will avoid failures seen in CI runs where the sync
thread failed because of a KeyError because some items where
concurrently removed from the NSX cache.

TripleO's multi-node testing shows that this patch caused a failure to receive

to have one agent port, the third to have 2 agent ports, etc. Needless to say,
this doesn't work all that well :)
