fix(ingest): fix types changes in clickhouse sqlalchemy 0.2.3

[mayurinehate]

Due to this change in clickhouse-sqlalchemy version 2.3.0, DataHub field type for "DateTime" and "DateTime64" is incorrectly represented as DateType instead of TimeType.
To add more context, Clickhouse types DateTime and DateTime64 are subclassed from sqlalchemy Date type instead of DateTime type, hence the above change caused inconsistent types in DataHub.
