feat, add replicat node to DA

[musitdev]

Summary

• RFCs: Link to RFC, Link to RFC, or $\emptyset$.
• Categories: any of protocol-units, networks, scripts, util, cicd, or misc.

Add a new node called replicat that streams block from DA and open a DA connection. Allow to provide DA connection in other regions in the world and replicate the DA db.

Changelog

• Create a new node that streams blocks from DA sequencer and stores them locally
• Open a block stream access, the same as the DA sequencer
• Allow to send batches. The whitelist configuration must be done on the replicat node.

To minimize the test to be done, most of the code is a copy-paste from da-sequecner to avoid changing too much code on the da side.

The da-dreplicat node will be installed on the follower node to have a DA db backup and on several regions, depending on the needs. I'll do the test with a node in Singapore that is already created..

Testing

To start the replicat node:

CELESTIA_LOG_LEVEL=FATAL nix develop --extra-experimental-features nix-command --extra-experimental-features flakes --command bash  -c "just movement-full-node native build.replicat --keep-tui"

To use the load test to similate some tx

CELESTIA_LOG_LEVEL=FATAL nix develop --extra-experimental-features nix-command --extra-experimental-features flakes --command bash  -c "just movement-full-node native build.replicat.load --keep-tui"
