feat: trustless-gateway block-brokers could accept multiaddrs/multiple uris?

Lines 45 to 51 in 375796a

	// take first address?
	// /ip4/x.x.x.x/tcp/31337/http
	// /ip4/x.x.x.x/tcp/31337/https
	// etc
	const uri = multiaddrToUri(httpAddresses[0])
	yield new TrustlessGateway(uri, logger)

Should we pass all multiaddrs to a trustless-gateway block-broker so it could fall back to others if the initial one isn't working?
