[telegraf-ds] support extra volume mounts, extra data in config map or secrets

I am trying to deploy a telegraf daemonset and I need to configure a certificate that has to be read from a file (specifically for the kafka output). Right now there is no way to do this (at least that I know of).

Would it be possible to add extra configuration either in the config map or in a secret to be able to do this?

Start by reviewing the telegraf daemonset chart's configuration for volume mounts, ConfigMaps, and Secrets. Trace how Kafka output settings are provided, then define done as allowing a certificate file and other extra data to be mounted and consumed by the deployment.
