Review Comment:
I believe using a distinct subclass of `MySQLConnectionProvider` would be
better, as it helps users distinguish between different engines(MySQL,Doris).
The presence of multiple connection providers does not impact user's
experience, and shouldn't throw an exception and terminate the process.
Instead, it should just remind users to set the
`ENGINE_JDBC_CONNECTION_PROVIDER` parameter.
