Collect more Metrics with Telegraf

[lawliet89]

Some of them can be run as Nomad Jobs.

• [ ] Consul service metrics
• [ ] Elasticsearch metrics. Circular dependency?
• [ ] Fluentd
• [ ] Docker on Nomad Clients

To Consider

• [ ] Cloudwatch to do alerting.
• [ ] "Grokking" logs for alerts instead of using Cloudwatch for: CloudTrail, VPC Flow Logs, application errors etc.
