TeamSpeak plugin "unexpected EOF" error

[dlmw]

Relevant telegraf.conf

[[inputs.teamspeak]]
  server = "teamspeak-host:10011"
  username = "monitoring"
  password = "MY_PASSWORD"
  nickname = "telegraf"
  [inputs.teamspeak.tags]
    service = "teamspeak"

Logs from Telegraf

2024-08-13T15:49:30Z E! [inputs.teamspeak] Error in plugin: unexpected EOF

System info

telegraf 1.31.2

Docker

No response

Steps to reproduce

1. Restart the telegraf service
2. Notice "nickname is already in use" error
3. After a while, the error transforms to "Error in plugin: unexpected EOF"

Expected behavior

The plugin should disconnect from ServerQuery gracefully in order to "free" the nickname.

Actual behavior

Nickname isn't freed. Potentially causing the EOF error down the line.

Additional info

Sometimes when telegraf is restarted, it has trouble connecting to the same TeamSpeak server because "nickname is already in use". The errors might be related.

It doesn't look like the plugin even try to disconnect. Would be happy to see a PR to clean this up, switch the plugin to a service plugin so the state and plugin attempt to connect + disconnect on stop.
