[Docs][Maps] Include details about the headers requested and served b…

…y EMS (elastic#171659) Fixes elastic#129751 ## Summary Extends the EMS documentation to detail request and response headers the browser sends to EMS resources and includes also a minimal `curl` command to request the response headers for same resource as well. I tried to edit this in a way it does not take the whole page but happy to hear feedback or ideas on how to make this easier to digest. https://github.com/elastic/kibana/assets/188264/27e83a5f-4d01-47a8-af2c-3739576bf56e Also, I am not sure if this is something worth adding to our release notes 🤔 (cherry picked from commit 0a7299b) # Conflicts: # docs/maps/connect-to-ems.asciidoc

 == Connect to Elastic Maps Service
 
+:ems-docker-repo: docker.elastic.co/elastic-maps-service/elastic-maps-server-ubi8
+:ems-docker-image: {ems-docker-repo}:{version}
+:ems-headers-url: https://deployment-host
+
 https://www.elastic.co/elastic-maps-service[Elastic Maps Service (EMS)] is a service that hosts
 tile layers and vector shapes of administrative boundaries.
 If you are using Kibana's out-of-the-box settings, Maps is already configured to use EMS.
 
+[float]
+=== Domains
+
 EMS requests are made to the following domains:
 
-* tiles.maps.elastic.co
-* vector.maps.elastic.co
+* Tile Service: `tiles.maps.elastic.co`
+* File Service: `vector.maps.elastic.co`
+
+[float]
+=== Headers
+
+Find below examples of the request and response headers from Kibana and a minimal `curl` request example showing the response headers sent by each service.
+
+WARNING: These headers may change without further notice at anytime and are shared for reference.
+
+[float]
+==== EMS Tile Service
+
+The EMS Tile Service provides basemaps in three different styles as the default background for Maps visualizations. The basemaps use https://www.openstreetmap.org/about[OpenStreetMap] data following the https://openmaptiles.org/[OpenMapTiles] schema and can be explored at https://maps.elastic.co[maps.elastic.co].
+
+Headers for the Tile Service JSON manifest describing the basemaps available.
+
+include::headers/tile-json.asciidoc[]
+
+Headers for a vector tile asset in _protobuffer_ format from the Tile Service.
+
+include::headers/tile-pbf.asciidoc[]
+
+Headers for an sprite image asset from the Tile Service
+
+include::headers/tile-png.asciidoc[]
+
+
+[float]
+==== EMS File Service
+
+EMS File Service provides the administrative boundaries used for <<maps-add-choropleth-layer,choropleth mapping>> as static assets in GeoJSON or TopoJSON formats and can be explored at https://maps.elastic.co[maps.elastic.co].
+
+Headers for the File Service JSON manifest that declares all the datasets available.
+
+include::headers/file-json.asciidoc[]
+
+Headers for a sample Dataset from the File Service in TopoJSON format.
+
+include::headers/file-data.asciidoc[]
 
-Maps makes requests directly from the browser to EMS.
