I think this RFC needs to be divided into two parts.

1. A RFC to go-endpoint to add TCP support
2. A RFC to hdfs to describe how will hdfs use endpoint (Maybe it's too clear that don't need a RFC)

It can be transferred to beyondstorage/go-endpoint/pull?
If not , may be merge 0-example and I go beyondstorage/go-endpoint again

No, we cannot.

If not , may be merge 0-example and I go beyondstorage/go-endpoint again

LGTM, let's remove the rfc-11 and just keep the example.
