Failed GRPC connections with reduced block time

[rnbguy]

When block time (timeout_commit in config.toml) is reduced, GRPC calls are failed. This is because, even though Tendermint has started to produce blocks, GRPC endpoints are not ready.

In the following code, .spinup() waits for RPC endpoints.

atomkraft/atomkraft/chain/testnet.py

Lines 310 to 330 in f95e408

	def spinup(self):
	for node in self.validator_nodes.values():
	node.start()
	for node in self.validator_nodes.values():
	while True:
	try:
	addr = node.get(
	self.ports()["rpc"].config_file,
	self.ports()["rpc"].property_path,
	)
	ip, port = addr.split("//")[-1].split(":")
	with socket.create_connection(
	(ip, port),
	timeout=5,
	):
	break
	except OSError:
	# todo: remove this sleep in future
	time.sleep(0.1)
	pass

But it should also wait for GRPC endpoints, probably for LCD/REST endpoints too.
