Martijn van Groningen 6aa9aaa2c6 Add validation for dynamic templates (#52890) ... Backport of #51233 to the seven dot x branch. Tries to load a `Mapper` instance for the mapping snippet of a dynamic template. This should catch things like using an analyzer that is undefined or mapping attributes that are unused. This is best effort: * If `{{name}}` placeholder is used in the mapping snippet then validation is skipped. * If `match_mapping_type` is not specified then validation is performed for all mapping types. If parsing succeeds with a single mapping type then this the dynamic mapping is considered valid. If is detected that a dynamic template mapping snippet is invalid at mapping update time then the mapping update is failed for indices created on 8.0.0-alpha1 and later. For indices created on prior version a deprecation warning is omitted instead. In 7.x clusters the mapping update will never fail in case of an invalid dynamic template mapping snippet and a deprecation warning will always be omitted.
