* Remove port name requirement
We now do protocol sniffing.
Note - this is definitely not safe to merge. We still need docs explaining protocol sniffing, and how to select a port type explicitly (required for things other than tcp/http, and more performant if you know its tcp/http). Not sure the path forward for this
* Add protocol selection doc
* Fix lint
* Add FAQ
When policy is set to an unrecognized value, the sidecar injector
defaults to [not injecting the pod, regardless of any other factors](https://github.com/istio/istio/blob/master/pkg/kube/inject/inject.go#L478)
This is different to the behvaior of `policy: disabled`, so the docs
should make that clear.
