PeerDAS Interop Milestones

Note: EIP7594_FORK_VERSION will be set to the same value as the Deneb fork and EIP7594_FORK_EPOCH will be set to 0 for the purposes of devnet-0.

Devnet-0 launched on 15th May 2024 and shut down on 31th May 2024.

[Spec merged] DataColumnSidecarsByRange added to the CL specs. PR: https://github.com/ethereum/consensus-specs/pull/3750

"devnet-0" version simplified FC: we don't do the full is_data_available check. Instead, the node checks if all columns of this block they are custodying are downloadable through either

1. Column subnets
2. Data column lookup over RPC

If they can, it's available. Otherwise, it's unavailable.

i.e. This milestone covers performing peer sampling, but does not including updating is_data_available based on sampling results.
