Added 1 additional cpu core metrics and 2 rollup disk metrics.
Added a configuration parameter to the disk plugin configuration
to enable/disable the aggregated disk metrics. Also added additional
documentation to the README file to reflect how to add dimensions
to a plugin instance.

The value_meta parameter was recently added to the
monasca-api. This allows the addition of meta-information
to be sent with any metrics that are sent from the agent.
value_meta was added for the http_status, nagios_wrapper,
and host_alive checks in the agent. Also, consolidated
some of the duplicate exception handling and reformatted
some code blocks.

Converted the config file to yaml and updated the config processing logic to match.
Cleaned up some deprecated config item processing.

Changed the IO, Disk and Network classes to not use a subprocess.
They now use psutil to get the metrics. Also, changed the linux
system metrics classes to subclass the AgentCheck class instead
of the old-style Check class. Added additional configuration
and changed monasca-setup to support that. Fixed some Python
2.6 incompatible string formatting issues.

The dimension handling was incorrect. It now follows this order of precedence:
1) Dimensions defined in a plugin config file
2) Dimensions that are defined in the agent config file
3) Dimensions that are defaults in a particular plugin
Also, updated imports to meet the OpenStack standards.

The section on the Libvirt plugin was unclear about how tenant
delegation needs to be set up, so hopefully this change makes
it a bit easier to understand.
Change-Id: I97a319d440c7b22d03829dfc50e2961fd6763f31
Renamed monagent package to monasca_agent and monsetup package to monasca_setup.
Also, renamed the monstatsd agent package to statsd to more closely match the internal
collector and forwarder packages.

Add monasca-setup's new 'amplifier' parameter to the README, and fix
a few minor spacing issues in monasca-setup's --help output.

The metric names and dimensions were not consistent throughout the
monasca-agent. Updated the documentation to match.

This patch gives the Monasca Agent the ability to monitor virtual
machines (VMs) provisioned under Nova. It bundles Ceilometer's
virtualization inspector to gather the actual metrics, includes a
monasca-setup plugin, and adds cross-tenant support. The latter
enables the Agent to submit metrics on behalf of a different
tenant/project, giving the VM's owner a set of metrics without each
VM having to run its own Agent. This plugin collects two sets of
measurements per metric: one for the VM's owner (in-cloud) and for
the Operations team (infrastructure). They differ in the following
ways:
- Operations metric names are prefixed with "vm." in order to group VM
and overcloud metrics separately
- Operations metrics include "tenant_id" as a dimension
- Operations metrics include "cloud_tier" dimension with the value
"overcloud"
- The "hostname" dimension for Operations contains the name of the
compute server; for the tenant, "hostname" is the name of the VM
The metrics gathered by this plugin include:
- Disk I/O: read/write operations/bytes per second
- Disk I/O: errors per second
- Network I/O: in/out packets/bytes per second
- CPU utilization as a percentage of CPU time over polling time
