Problems about Authentication and Security

[Juckey]

Does client code need user and password to access vtgate?If not, then any code can access vtgate without any authentication,i.e. client code can access databases behind vttablets directly, then perhaps security problems occur.

@alainjobart can comment more on this.
We already support SASL authentication for the current RPC framework we're using. However, we're also looking at transitioning to grpc, which has authentication built into its design as well as many other cool features.
