Chris Dearborn f6da45d11f Add ability to specify IP for service 
The problem that this change addresses is that the address_for method
will not work correctly if there are multiple IP address associated
with the specified interface.

The approach to solving this problem and moving towards the overall
goal of having one place where service networking information is
stored is to convert address_for calls into endpoints, and add a
address() method to the endpoints interface for IP address resolution.

The address() method has the following behavior: if the
bind_interface of an endpoint is set, then the IP is looked up on
the interface.  Otherwise, the IP specified in the host attribute is
returned.  This allows the caller to choose either method of
determining what IP a service will be bound to.

This initial change switches both the openstack-ops-database and
openstack-ops-messaging cookbooks over to use endpoints instead of
address_for.  The other cookbooks will be switched over time.

# ======================== OpenStack DB Support ================================
#
# This section of node attributes stores information about the database hosts
# used in an OpenStack deployment.
#
# There is no 'scheme' key. Instead, there is a 'service_type' key that should
# contain one of 'sqlite', 'mysql', or 'postgresql'
#
# The ::Openstack::db(<SERVICE_NAME>) library routine allows a lookup from any recipe
# to this array, returning the host information for the server that contains
# the database for <SERVICE_NAME>, where <SERVICE_NAME> is one of 'compute' (Nova),
# 'image' (Glance), 'identity' (Keystone), 'network' (Neutron), or 'volume' (Cinder)
#
# The ::Openstack::db_connection(<SERVICE_NAME>, <USER>, <PASSWORD>) library routine
# returns the SQLAlchemy DB URI for <SERVICE_NAME>, with the supplied user and password
# that a calling service might be using when connecting to the database.
#
# For example, let's assume that the database that is used by the OpenStack Identity
# service (Keystone) is configured as follows:
#
# host: 192.168.0.3
# port: 3306
# service_type: mysql
# db_name: keystone
#
# Further suppose that a node running the OpenStack Identity API service needs to
# connect to the above identity database server. It has the following in it's node
# attributes:
#
# node['openstack']['db']['identity']['username'] = 'keystone'
#
# In a 'keystone' recipe, you might find the following code:
#
# user = node['openstack']['db']['identity']['username']
# pass = get_password 'db', 'keystone'
#
# sql_connection = ::Openstack::db_uri('identity', user, pass)
#
# The sql_connection variable would then be set to "mysql://keystone:password@192.168.0.3:keystone"
# and could then be written to the keystone.conf file in a template.
#
# Database Migrations:
#
# node['openstack']['db'][<SERVICE_NAME>]['migrate']
#
# The above attribute causes database migrations to be executed for the given
# service. There are cases where migrations should not be executed. For
# example when upgrading a zone, and the image or identity database are replicated
# across many zones.
