1. Reference to Flink Doris Connecotor through DataStream will be affected (FlinkSQL will not be affected)
The current package path of Flink Doris Connector is org.apache.doris. After migrating to the Flink community, the path may become org.apache.flink.connector.doris. For the DataStream program written by the user, the job may need to be modified.

2. Considering that Flink Doris Connector(https://github.com/apache/doris-flink-connector) is already organized in Apache, I think we can just transfer the ownership of the project and rename it. This avoids the need to recreate the project and push code.

Test Plan

1. Unit test cases to test methods in Flink Doris Connector.
2. The E2E test suite will be added in flink-connector-doris-e2e-tests.
