Telegraf deprecation warnings

[Paraphraser]

While I was testing Telegraf as part of preparing a response to PR554, I noticed the following deprecation warnings:

2022-04-30T02:19:39Z I! Using config file: /etc/telegraf/telegraf.conf
2022-04-30T02:19:39Z W! DeprecationWarning: Option "container_names" of plugin "inputs.docker" deprecated since version 1.4.0 and will be removed in 2.0.0: use 'container_name_include' instead
2022-04-30T02:19:39Z W! DeprecationWarning: Option "total" of plugin "inputs.docker" deprecated since version 1.18.0 and will be removed in 2.0.0: use 'total_include' instead
2022-04-30T02:19:39Z I! Starting Telegraf 1.22.3

I'm opening this issue so these warnings don't get ignored until too late.
