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`.

This change corrects the detected sphinx-linit issue in the existing
docs and updates the contributor devstack guide to call out
required and advanced.
mostly the changes were simple fixes like replacing the configurable

This patch does two things:
1. replace instance's human_id with name.
2. remove ComputeNode human_id.
Now name field in Watcher Compute Data Model is availible.
Use name is better than human_id. For the reason, please see[1].
