Support Advanced Distribution

[amouat]

One of the first goals of Trow was to become a production version of ImageWolf. ImageWolf used bittorrent to rapidly move images onto nodes.

Since then we have had Kraken and DragonFly which pursued similar goals.

In contrast to those projects, advanced distribution in Trow should be very minimal and simple to configure and use - it should more or less work out of the box.

The plan for advanced distribution instructed the architecture and design of Trow and is the reason for gRPC and the frontend/backend. More information can be seen in the architecture doc

This issue should track progress and be broken down into multiple sub-tasks (which is itself the first task ;) )

Hi. I'm interested in the distribution feature. Do you have some updates about the CRDT implementation? I could contribute some time to it.
And I had another idea which maybe makes things easier. Base on the arch img in https://github.com/ContainerSolutions/trow/blob/main/docs/ARCHITECTURE.md#advanced-distribution-deployment , all trow-backends are equality. Could we make two kinds of backend? One is for write/push, another is for read/pull. And put a router in front of them.
