ZhiQiang Fan 9c3278c942 configure Apache only when ceilometer-api is enabled
Currently, even though ceilometer-api service is disabled by user,
we still try to configure ceilometer-api in Apache if CEILOMETER_USE_MOD_WSGI
is not set to false. This patch adds a constraint to ensure we only
configure when ceilometer-api is enabled.

# Install and start **Ceilometer** service in devstack
#
# To enable Ceilometer in devstack add an entry to local.conf that
# looks like
#
# [[local|localrc]]
# enable_plugin ceilometer git://git.openstack.org/openstack/ceilometer
#
# By default all ceilometer services are started (see
# devstack/settings). To disable a specific service use the
# disable_service function. For example to turn off alarming:
#
# disable_service ceilometer-alarm-notifier ceilometer-alarm-evaluator
#
# NOTE: Currently, there are two ways to get the IPMI based meters in
# OpenStack. One way is to configure Ironic conductor to report those meters
# for the nodes managed by Ironic and to have Ceilometer notification
# agent to collect them. Ironic by default does NOT enable that reporting
# functionality. So in order to do so, users need to set the option of
# conductor.send_sensor_data to true in the ironic.conf configuration file
# for the Ironic conductor service, and also enable the
# ceilometer-anotification service. If you do this disable the IPMI
# polling agent:
#
# disable_service ceilometer-aipmi
#
# The other way is to use Ceilometer ipmi agent only to get the IPMI based
# meters. To avoid duplicated meters, users need to make sure to set the
# option of conductor.send_sensor_data to false in the ironic.conf
# configuration file if the node on which Ceilometer ipmi agent is running
# is also managed by Ironic.
#
# Several variables set in the localrc section adjust common behaviors
# of Ceilometer (see within for additional settings):
#
# CEILOMETER_PIPELINE_INTERVAL: Seconds between pipeline processing runs. Default 600.
# CEILOMETER_BACKEND: Database backend (e.g. 'mysql', 'mongodb', 'es')
# CEILOMETER_COORDINATION_URL: URL for group membership service provided by tooz.
# CEILOMETER_EVENTS: Set to True to enable event collection
# CEILOMETER_EVENT_ALARM: Set to True to enable publisher for event alarming
# Save trace setting
