Add detection of source.mode synthetics for 8.17.2 onwards

[mrodm]

Relates #2397

This PR adds support to detect synthetic mode from 8.17.2 onwards.

It looks like that starting in this version this mode is declared under the settings object:

{ "template": { "settings": { "index": { "mapping": { "total_fields": { "limit": "1000", "ignore_dynamic_beyond_limit": "true" }, "source": { "mode": "synthetic" } }, } } } }

Before this (in 8.17.1), there is also a warning message in the API response:

#! Configuring source mode in mappings is deprecated and will be removed in future versions. Use [index.mapping.source.mode] index setting instead. { "template": { "mappings": { "_source": { "mode": "synthetic" } } } }
