### Description

**Background**
As part of https://github.com/elastic/kibana/issues/104986 we will be adding the ability for Elastic Agents to send agent monitoring data to a remote Elasticsearch cluster. In order to achieve this, we will need a service token for the remote cluster which fleet server will use. 

This service account will need less permissions than the `elastic/fleet-server` as integration data will not be sent to remote clusters yet.

**Service Account Details**

Name: `elastic/fleet-server-remote`

Permissions:
-  for indices `logs-*`, `metrics-*` privileges "write", "create_index", "auto_configure"
