feat(telegraf, grafana): Start collecting redis metrics

Also updates the configuration of telegraf to update the following
values:
* collection_jitter - 1s
* flush_interval - 1s

Sets the collection interval for nsq metrics to 1s (not the nsq_consumer
plugin)

Updates the dashboards to remove redundant fields and set the version
value to 0.
