Allow adding annotations to Logzio-k8s-logs/filebeat chart

[Aransh]

Can't see a way currently to set additional annotations to the filbeat daemonset.

In my use case, the Logzio token comes from an external pre-existing kubernetes secret, I want to configure the daemonset to restart if this secret is updated, to apply updated tokens. This can be done using Reloader, but this requires setting an annotation on the daemonset to configure.
