feature: expose elasticsearch action results as metric

[uatmaca]

we need to expose elasticsearch actions metrics to prometheus endpoint.

example metrics:
es_action_success_total
es_action_error_total
es_action_total

or

es_action_total{result="success/error", action="delete/index"}

What are their use cases? How can you use it after exposure, what kind of alerts, etc? 🤔

We want to define alert. If there is any problem, we want to fix it 🙃 For example complex data type issues (GeoShape etc)
