fix(telegraf) ensure off-cluster influxdb url is quoted

[croemmich]

When using an off-cluster influxdb, the outputs.influxdb.urls array is set improperly, as the singular config value is pulled from the secret and not quoted. See below:

Building config.toml!
Finished building toml...
###########################################
###########################################
...
[[outputs.influxdb]]
  urls = [https://influx01:8086]
  database = "deis"
  precision = "ns"
  timeout = "5s"
   username = "deis" 
   password = "..." 
 ...
###########################################
###########################################
2017/03/13 04:49:40 E! Error parsing config.toml, toml: line 17: parse error

This could be fixed a few ways. The safest and most strait-forward would be to only allow a single url and executing the | quote filter on the value. However, it appears the original author intended on keeping the ability to add multiple urls. This fix, although slightly hack-ish, allows for proper handling of the off-cluster influx configuration or the quoted default (or other) configuration.

So we are currently moving away from using our own influxdb chart to the one in the stable repo. This will allow us to more easily consume upstream changes directly from influx rather than having to incorporate them into our chart. Because of this I want to hold off on merging this change until we get the new chart in place and the migration.

ping @jchauncey, any word on the influx/grafana/telegraf migration?

It's dependent right now on a change I'm putting in helm
