Support implement UDF through GRPC protocol. This brings several benefits: 1. The udf implementation language is not limited to c++, users can use any familiar language to implement udf 2. UDF is decoupled from Doris, udf will not cause doris coredump, udf computing resources are separated from doris, and doris services are not affected But RPC's UDF has a fixed overhead, so its performance is much slower than C++ UDF, especially when the amount of data is large. Create function like ``` CREATE FUNCTION rpc_add(INT, INT) RETURNS INT PROPERTIES ( "SYMBOL"="add_int", "OBJECT_FILE"="127.0.0.1:9999", "TYPE"="RPC" ); ``` Function service need to implement `check_fn` and `fn_call` methods Note: THIS IS AN EXPERIMENTAL FEATURE, THE INTERFACE AND DATA STRUCTURE MAY BE CHANGED IN FUTURE !!!
