DAL: Rollup node supports injecting DAL slots

Mohamed IGUERNLALArequested to merge
iguerNL@rollup-node-supports-injecting-dal-slots into master

What

This MR extends the rollup node with an RPC (and a worker) to be able to publish DAL slots to L1 and DAL networks via the rollup node.

Why

This feature will be used by the Etherlink sequencer to publish (chuncks of) L2 blueprints into L1/DAL.

How

  • Added a new kind of L1 operations Publish_dal_commitment, similar to Add_messages
  • Added a new worker that serves as a proxy between the new /dal/injection RPC and the rollup's L1 operations injector
  • Configured the rollup node to behave much like batched messages injection to L1 (amount of operations fees, purpose, injection strategy, ...)

Testing

See !13818 (merged)
