Feature/additional elasticsearch options

[ghost]

What this PR does / why we need it:

This PR adds a couple of options to the out_elasticsearch and out_elasticsearch_data_stream fluentd plugins.
It implements the options in #1210 and then some more.

I needed to update controller-gen to a newer version as v0.11.3 did not support go 1.22.

Which issue(s) this PR fixes:

Fixes #1210

Does this PR introduced a user-facing change?

Added options for ILM to fluentd out_elasticsearch and out_elasticsearch_data_stream plugin
