[Bug]: operations missing param check

[zhengbuqian]

for example grpc_handler.py::search calls check_pass_param‎ but is not passing param to check_pass_param‎. Some other operations such as create_index, insert and upsert doesn't call check_pass_param‎ at all.

Even if we have server side check, we should still check those prior sending the RPC. We have the checkers already anyway, we should use them.
