Add the 'external' message bus configuration option

This option is used to run devstack against a pre-provisioned
message bus, rather than having this plugin setup the bus.

#
# Environment Configuration
#
# AMQP1_SERVICE - identifies the messaging backend to use. Should be
# one of 'qpid' for broker backend, 'qpid-dual' for hybrid router-broker, or
# 'qpid-hybrid' for keeping Rabbit for notifcations.
# @TODO(kgiusti) add qpid-dispatch, etc
# AMQP1_SERVICE - This plugin can deploy one of several different
# message bus configurations. This variable identifies the message
# bus configuration that will be used. Should be one of:
# 'qpid' - use the qpidd broker for both RPC and Notifications
# 'qpid-dual' - use qpidd for Notifications, qdrouterd for RPC
# 'qpid-hybrid' - use rabbitmq for Notifications, qdrouterd for RPC
# 'external' - use a pre-provisioned message bus. This prevents
# this plugin from creating the message bus. Instead it assumes
# the bus has already been set up and simply connects to it.
# AMQP1_RPC_TRANSPORT_URL - Transport URL to use for RPC service
# AMQP1_NOTIFY_TRANSPORT_URL - Transport URL to use for Notification
# service.
#
# If the above AMQP1_*_TRANSPORT_URL env vars are not defined, this
# plugin will construct these urls using the following env vars:
#
# AMQP1_HOST - the host used to connect to the messaging service.
# Defaults to 127.0.0.1
# AMQP1_{DEFAULT_PORT, NOTIFY_PORT} - the port used to connect to the messaging
# service. Defaults to 5672 and 5671.
# AMQP1_{USERNAME,PASSWORD} - for authentication with AMQP1_HOST
# Defaults to $SERVICE_HOST
# AMQP1_{DEFAULT_PORT, NOTIFY_PORT} - the port used to connect to the
# messaging service. AMQP1_NOTIFY_PORT defaults to 5672.
# AMQP_DEFAULT_PORT also defaults to 5672 for the 'qpid'
# configuration, otherwise 45672 to avoid port# clashes with the
# Notification port.
# AMQP1_{USERNAME,PASSWORD} - for authentication with AMQP1_HOST (optional)
#
# The RPC transport url will be defined as:
# "amqp://$AMQP1_USERNAME:$AMQP1_PASSWORD@$AMQP1_HOST:${AMQP1_DEFAULT_PORT}/"
#
# The notify transport url will be defined as:
# "amqp://$AMQP1_USERNAME:$AMQP1_PASSWORD@$AMQP1_HOST:${AMQP1_NOTIFY_PORT}/"
