Add `JSON` datatype, following features are implemented by this PR: 1. `CREATE` tables with `JSON` type columns 2. `INSERT` values containing `JSON` type value stored in `String`, which is represented as binary format(AKA `JSONB`) at BE 3. `SELECT` JSON columns Detail design refers [DSIP-016: Support JSON type](https://cwiki.apache.org/confluence/display/DORIS/DSIP-016%3A+Support+JSON+type) * add JSONB data storage format type * fix JsonLiteral resolve bug * add DataTypeJson case in data_type_factory * add JSON syntax check in FE * add operators for jsonb_document, currently not support comparison between any JSON type value * add ColumnJson and DataTypeJson * add JsonField to store JsonValue * add JsonValue to convert String JSON to BINARY JSON and JsonLiteral case for vliteral * add push_json for MysqlResultWriter * JSON column need no zone_map_index * Revert "JSON column need no zone_map_index" This reverts commit f71d1ce1ded9dbae44a5d58abcec338816b70d79. * add JSON writer and reader, ignore zone-map for JSON column * add json_to_string for DataTypeJson * add olap_data_convertor for JSON type * add some enum * add OLAP_FIELD_TYPE_JSON type, FieldTypeTraits for it and corresponding cases or functions * fix column_json offsets overflow bug, format code * remove useless TODOs, add CmpType cases for JSON type * add license header * format license * format be codes * resolve rebase master conflicts * fix bugs for CREATE and meta related code * refactor JsonValue constructors, add fe JSON cases and fix some bugs, reformat codes * modification be codes along code review advice * fix rebase conflicts with master * add unit test for json_value and column_json * fix rebase error * rename json to jsonb * fix some data convert bugs, set Mysql type to JSON
