Implement base app-gateway contract for frontend

[faraonc]

Feature

hwsc-org/hwsc-app-gateway-svc#9

Below are the initial expected services for the frontend.
These services are NOT the same with the other services.

For example:

rpc CreateUser (AppGatewayServiceRequest) returns (AppGatewayServiceResponse) {} will use
hwsc-user-svc's CreateUser and hwsc-file-transaction-svc's CreateUserFolder

    rpc GetStatus (AppGatewayServiceRequest) returns (AppGatewayServiceResponse) {}
    rpc CreateUser (AppGatewayServiceRequest) returns (AppGatewayServiceResponse) {}
    rpc DeleteUser (AppGatewayServiceRequest) returns (AppGatewayServiceResponse) {}
    rpc UpdateUser (AppGatewayServiceRequest) returns (AppGatewayServiceResponse) {}
    rpc AuthenticateUser (AppGatewayServiceRequest) returns (AppGatewayServiceResponse) {}
    rpc ListUsers (AppGatewayServiceRequest) returns (AppGatewayServiceResponse) {}
    rpc GetUser (AppGatewayServiceRequest) returns (AppGatewayServiceResponse) {}
    rpc ShareDocument (AppGatewayServiceRequest) returns (AppGatewayServiceResponse) {}
    rpc CreateDocument (AppGatewayServiceRequest) returns (AppGatewayServiceResponse) {}
    rpc ListUserDocumentCollection (AppGatewayServiceRequest) returns (AppGatewayServiceResponse) {}
    rpc UpdateDocument (AppGatewayServiceRequest) returns (AppGatewayServiceResponse) {}
    rpc DeleteDocument (AppGatewayServiceRequest) returns (AppGatewayServiceResponse) {}
    rpc AddFile (AppGatewayServiceRequest) returns (AppGatewayServiceResponse) {}
    rpc DeleteFile (AppGatewayServiceRequest) returns (AppGatewayServiceResponse) {}
    rpc ListDistinctFieldValues (AppGatewayServiceRequest) returns (AppGatewayServiceResponse) {}
    rpc QueryDocument (AppGatewayServiceRequest) returns (AppGatewayServiceResponse) {}

What about filter related calls? Such as getting a list of publishers getting a list of unique instruments, etc

Is ListDistinctFieldValues have something to do with that?

I just realized that I am doing all of that with one RPC call using ListDistinctFieldValues, but yes, ListDistinctFieldValues does that. It may need to be separated later on.
