Missing ceilometer configuration in swift-proxy conf

[Hemanth Nakkina]

During redeployment or custom graph execution, ceilometer related configuration is missing in swift-proxy.conf. ( No issue with configuration if first/initial deployment is successful)

Working case - swift-proxy.conf
[pipeline:main]
pipeline = catch_errors crossdomain healthcheck cache bulk tempurl ratelimit formpost swift3 s3token authtoken keystone staticweb container_quotas account_quotas slo ceilometer proxy-server

[filter:ceilometer]
use = egg:ceilometer#swift

Non-working case - swift-proxy.conf
[pipeline:main]
pipeline = catch_errors crossdomain healthcheck cache bulk tempurl ratelimit formpost swift3 s3token authtoken keystone staticweb container_quotas account_quotas slo proxy-server

Analysis
--------
Hiera parameter use_ceilometer is not properly updated during the error scenario which inturn is required to populate ceilometer configuration in swift-proxy.conf.

Working case
     fuel@aic-controller-001:~$ sudo hiera use_ceilometer
     true

Non-working case
    fuel@aic-controller-001:~$ sudo hiera use_ceilometer
    nil

use_ceilometer is set when ceilometer hiera have enabled paramter TRUE.

In non-working case,

hiera ceilometer
{"compute_monitors"=>"ComputeDriverCPUMonitor,ComputeDriverNicMonitor",
"default_notification_level"=>"INFO",
"event_time_to_live"=>"3024000",
"ha_mode"=>false,
"metering_time_to_live"=>"3024000",
"notification_driver"=>"messagingv2",
"notification_topics"=>
  "lma_notifications,monitor,dnsnotifications,notifications"}

hiera -h ceilometer
{"db_password"=>"ynY2To1WSTyrF5ZKUb2BsWRI",
"enabled"=>true,
"metering_secret"=>"OAqoxvIw6SZtUV2fRPtI8F3Y",
"user_password"=>"q6qUDjfrIP6hD60wHUy9h3Yk",
"alarm_history_time_to_live"=>"604800",
"event_time_to_live"=>"3024000",
"metering_time_to_live"=>"3024000",
"http_timeout"=>"600",
"notification_driver"=>"messagingv2",
"compute_monitors"=>"ComputeDriverCPUMonitor,ComputeDriverNicMonitor",
"default_notification_level"=>"INFO",
"ha_mode"=>false,
"notification_topics"=>
  "lma_notifications,monitor,dnsnotifications,notifications"}

So proposal is to modify globals.pp to use hiera hash instead of hiera.
