Ceilometer role for OpenStack-Ansible

Ceilometer role for OpenStack-Ansible

This Ansible role installs and configures OpenStack ceilometer.

Meter and notification storage is configured to use a MongoDB backend by default. This role does not install and configure the MongoDB backend. Deployers wishing to use MongoDB must install and configure it prior to using this role and override ceilometer_connection_string variable with MongoDB connection details.
