Use bls to gather signatures on proofs from nodes in switching process.

[mchitgarha78]

This part of code should be updated with bls aggregation on proofs:

zsequencer/node/tasks.py

Lines 285 to 295 in 5081ee5

	def send_switch_requests(proofs: list[dict[str, Any]]) -> None:
	"""Send switch requests to all nodes except self."""
	zlogger.info("sending switch requests...")
	for node in zconfig.NODES.values():
	if node["id"] == zconfig.NODE["id"]:
	continue
	data: str = json.dumps(
	{
	"proofs": proofs,
	"timestamp": int(time.time()),

Lets do this after initial release on EigenLayer holesky testnet
