Use a single method to remove an address with its conntrack state

the ip_lib paradigm of wrapping ip commands without any additional
useful abstraction. Any better ideas?

Add sub-project lieutenants
A recent patch added the concept of Lieutenants for Neutron. This
same concept makes a lot of sense for identifying clear points of
contact for the various sub-projects under the Neutron tent. This
patch adds a table of the projects currently approved as part of
Neutron in the governance repo. I also made a guess on who the
lieutenant would be based on reviews in stackalytics (except for ones
that weren't in stackalytics).

Wrap ML2 delete_port with db retry decorator
ML2 delete_port operation currently involves locking ports
and bindings tables which may lead to DBDeadlock errors in certain
cases when several ports are deleted concurrently.
That may happen due to specifics of Galera working in active-active
mode: it may throw deadlock errors when it fails to validate
a change with other members of the cluster.
The fix adds retries to delete port operation to overcome such
deadlocks

Catch broad exception in methods used in FixedIntervalLoopingCall
Unlike other places where it might make sense to catch specific
exceptions, methods that are used to check L3 and DHCP agents
liveness via FixedIntervalLoopingCall should never allow exceptions
to leak to calling method and interrupt the loop.
Further improvement of FixedIntervalLoopingCall might be needed,
but for the sake of easy backporting it makes sense to fix the issue
in neutron before pushing refactoring to 3rd-party library.

Update rootwrap.conf to add /usr/local/bin
When working with OVN i found on Fedora 21 that

Don't delete port from bridge on delete_port event
Commit d6a55c17360d1aa8ca91849199987ae71e8600ee added
logic to the OVS agent to delete a port from the integration
bridge when a port was deleted on the Neutron side. However,
this led to several races where whoever created the initial
port (e.g. Nova, L3 agent, DHCP agent) would be trying to
remove the port from the bridge at the same time. These
would result in ugly exceptions on one side or the other.
The original commit was trying to address the problem where
the port would maintain connectivity even though it was removed
from the integration bridge.
This patch addresses both cases by removing the iptables rules
for the deleted port and putting it in the dead VLAN so it loses
connectivity. However, it still leaves the port attached to the
integration bridge so the original creator can delete it.

Use correct time delta function
