Engineer can start the data archiver with RPC endpoint and rollup contract configuration

[PhilWindle]

It should be possible to start the data archiver with configuration for an Ethereum host, a rollup contract, a starting block and a persistence interface.

@PhilWindle what do you mean by persistence interface?

[PhilWindle]

@benesjan I mean that the archiver should be written in a way that abstracts how the data is stored. So it should take an argument that is merely an interface to storing/retrieving whatever data is required. The concrete implementation of that interface could be a db or a filesystem or just a set of in memory data structures.

In fact, the other arguments I have specified are incorrect. It should take an interface that abstracts the ethereum host, rollup contract etc away.
