We map `text` and `keyword` both to `string` type in Doris. When enable `like_push_down`, we translate like to wildcard query in ES, which will lead unexpected result in `text` field. We should stick to `keyword` with wildcard query. 1. Add `column2typeMap` in `EsTable` to save the mapping of column_name to ES field data type. 2. Add new class `EsSchemaCacheValue` to get schema and column to type map 2. Init `column2typeMap` when cache init and build query process of ES external table
2. Add end to end test case for like.
