Add grafana 
This change introduces grafana into the stack which gives us a great
way to visualize the data. The grafana role from cloudalchemy is being
used for the bulk of the deployment.

Because the grafana deployment playbook is now standalone the mentions
of grafana in the other ops directories have been removed.

9e706b13a3 Add prometheus_client as optional output 
Currently the only outputs plugin used is influxdb. This adds
prometheus_client outputs plugin and its directives as options.
The telegraf.conf.j2 template has been updated to check for the
outputs_prometheus_client variable and two other related variables.
New variable names and default values are shown in vars.yml.

c1f7a5b2fb Added playbook to deploy Kapacitor 
Added a playbook to deploy an alerting tool, Kapacitor that can work
with influxdb. Updated readme to demonstrate how to deploy Kapacitor.

Kapacitor can be used to trigger alerts based on some uncertain
events. It subscribes to influxdb to collect data.

General Flow:
Telegraf -> InfluxDb -> Grafana
Telegraf -> InfluxDb -> Kapacitor
