[7.17] [ML] Allow retrieving
boolean
fields from _source in DFA jobs (
#85672) (#85723) This commit fixes a bug where `boolean` mapped fields may only be retrieved from doc values in Data Frame Analytics jobs. While this problem may occur for `boolean` fields with disabled doc values, a more common way of being affected by this bug is running an analysis against data with a very high number of fields. If there are more fields than the `index.max_docvalue_fields_search` setting, we fall back to retrieving the fields from _source. Then `boolean` mapped fields would fail with the error message "cannot apply boolean mapping to field [<field>]".
