bitcoin-cli -rpcwaitworks probably as expected if the blocks are loading before core lightning start. But doesn't if BitcoinD isn't listening at all before Core Lightning wait, we observed the following behavior.Rather than waiting for 30 seconds, this PR wait 30 times for 1 seconds. This fix the issue for us.
This is a patch we are using in BTCPay Server deployments. Not really critical in production scenario, but it was causing our tests to fail as lightningd was taking 30 seconds to properly start.
