In order to support vm_workload_consolidation, workload_balance and workload_stabilization strategis some instance metrics are required. This patch is adding support for them. Implementation is based on a prometheus store populated using sg-core from ceilometer metrics with Pollster source. - instance_ram_usage: rely on ceilometer_memory_usage metrics created from ceilometer memory.usage meter. - instance_ram_allocated: rely on the memory value provided by the inventory created from nova and placement APIs. - instance_cpu_usage: rely on ceilometer_cpu metric created from ceilometer cpu meter. A max value of 100 is set in the query. - instance_root_disk_size: rely on the `disk` value provided by the inventory created from nova and placement APIs. A new parameterer `instance_uuid_label` has been added to the prometheus datasource configuration to identify the label used to store the value of the OpenStack instance uuid for eache instance metric in prometheus. Default value is `resource`. Change-Id: I2f2b56aa002014e511a5e48398ef1da43fc4f5e2
