[hoslo]

Part #4177

@Xuanwo Basically done, do you have any suggestions for users to use different protocols to access memcache? sasl is only available in bianry.

[Xuanwo]

Please don't add services in default set.

I'm not certain, but it seems like binary consistently outperforms ascii, doesn't it? Do you have a basic bench about them?

It seems that the binary protocol is a bit faster than the ascii protocol and supports authentication.

That's great! We can remove ascii support.

Would you like to add a test for memcached with password? And do we need sasl at client side?

Yes, I will add it in another pr, we do not need sasl at client side.

Got it. Let's move!
