How to add authentication to go-micro/api?

[ryanrain2016]

I want to add authentication to the gateway implemented with go-micro/api, but I don't know how to do it. Seems like the api doesn't implement something like middleware. Is there any other way to add an authentication method to the gateway?

Are changes to make Auth work in go-micro.

Else you might wait for go-orb to be done.
