Loki: Scale out single binary mode

[gouthamve]

Currently the all-in-one (run locally) mode requires no X-Scope-OrgID header. I am not sure if that could be the case for the distributed mode too. Most users of Loki won't need multi-tenancy and not having a gateway would help.

It shouldn't be needed, no - we have some middleware that injects a fake header to the no-auth mode. Making the single binary distributed mode work needs:

• [x] a replacement for consul for distributing the ring; weaveworks/mesh?
• [x] a flag to cause the ingesters to also query the (local) chunk store - with the micro service design, the queriers would do this independently
• [ ] docs

I'll hijack this issue for "scale out single binary mode" now.

Any update on this topic? Is it now possible to scale single binary (helm) setup into multiple replicas? Looks like different ring configs can be provided: https://github.com/sboschman/loki/blob/master/production/helm/loki/values.yaml#L33

We are most of the way to being able to support this, I think it needs better documentation and some testing.
