any reason of adding this interceptor?

[brcarry]

any reason of adding this interceptor?

For authentication and configuration.
For example, when you login using username and password, you need to add the corresponding authentication key-value pair to gRPC request header through an interceptor. Like pymilvus, an interceptor can also be used to add key-value pairs to gRPC request header for configuring database to use, log_level, client_request_id.
