This patch makes it possible to maintain several redis hosts at
once in order to increase driver's reliability and fault tolerance.

'Notification Listener' doesn't work.
I fixed the example which is described in developer guide to work fine.
These are the main points of this correction.
* specify namespace for NotificationFilter.
* set 2 blank lines between class definitions according to E302 of pep8.
* change argument of 'pool' to keyward arguemnt, because 4th argument of
'get_notification_listener' requires the name of message executor.

If the remote target and the caller have different python
versions, then built-in exceptions raised by the remote target
will not be properly deserialized on the caller. Because of this,
oslo.messaging will simply raise a RemoteError, instead of any
expected exceptions the caller might expect.
This patch addresses this issue.

This patch moves message sending closer to ack receiving. As a
result we get more uniform load on servers and more reliable
behavior when some proxies suddenly shut down.

Decrease the size of the debug log output drastically by removing
debug messages issued for each message. This patch only removes those
log statements that log correct behavior - errant behavior is still
logged for debug.

* Refactored RoutingTable, in order to work on string target
representation.
* RoutingTableAdaptor - provides usable adaptation of RoutingTable
to use with Target object.
* RoutingTableUpdater - implements asynchronous table updates
from the matchmaker.
* Implemented dynamic connections for DealerPublisherDirect
* Use dynamic connections for direct messages

--debug, --is-cast and --is-fanout are defined as args of type=bool.
This means that, for example, if we want to enable debug logging
level, we have to type '--debug True'. But we can also use
'--debug False' in order to do the same, which is very misleading
(in fact, any non-empty string will evaluate to True). This patch
tries to solve this problem by replacing type=bool and
default=False with action='store_true' for these args, so that
we will be able to enable them (they will remain False by default
as before) simply as '--debug' etc.

Since proxy supposed to be used in different configurations
second ROUTER socket may stay unused (e.g. when we use proxy
for publishing only fanout messages in mixed direct/pub-sub
configuration see ZmqClientMixDirectPubSub).
This patch introduces two modes of proxy SingleRouterProxy (where
frontend and backend ROUTERS are the same socket) and
DoubleRouterProxy (different sockets for the frontend and for the
backend - the original behavior).

The MatchmakerRedis depends on 'redis' package, but there is no error
handler in it.
This patch adds processing to raise an exception when 'redis' package
doesn't exist.

According to the RabbitMQ client docs [1], the only valid login
methods are: PLAIN, AMQPLAIN, or RABBIT-CR-DEMO. This patch restricts
the rabbit driver to only those options.

This patch simply replaces all delimeters used for generating
internal identifiers like redis keys or socket identities
with slashes (since they are visually better for debugging than
dots, hyphens or underscores, which may also occur inside
topic or server names).

This patch fix incorrect fanout behavior when use_pub_sub=False.
In addition it also makes dummy matchmaker behave similar to (already
fixed here) redis one in order to make future testing more realistic
(relevant tests were also fixed and refactored).

During rally tests it was discovered that the latency between
receiving message and dispatching it can reach up to 10 minutes.
This behaviour breaks the mechanism of acks and retries in zmq driver,
which causes test failures. This patch tries to fix these problems
by moving ack sending from rpc server's thread to zmq dealer
consumer's thread (immediately after message receiving).

In oslo_messaging/_drivers/impl_rabbit.py, the documentation of
the Consumer class is the following: """Init the Publisher class
with the exchange_name, routing_key, type, durable auto_delete""".
This should be corrected by putting Consumer instead of Publisher.

Rework the inline documentation for executors, RPC servers and
clients, notifiers and notification listeners for clarity and flow.

Consumer declaration consist of the next steps:
1) declare an exchange
2) declare a queue
3) bind the queue to the exchange
Due to reply exchanges are auto-delete, at the
step 3 the exchange can be removed and consumer.declare()
will raise `queue.bind 404 Exchange not found`.
So, in this case the queue is exist and AMQPListener
just call consumer.consume() on the queue and go to
drain_events() despite on the fact that the queue is
unbound.
This change tries to redeclare queue/exchange proactively
each times channel change and just before consuming messages.
