Add logger when worker is waiting for master to connect

[alvaro-ajv]

Want to add a logger to the runners.py when worker is waiting for the master to be running, I already have the code but I need access to push the branch. Also want to start contributing to this repo. Thanks

Code:

    def connect_to_master(self):
        self.retry += 1
        logger.info("Waiting for master to be ready")
        self.client.send(Message("client_ready", __version__, self.client_id))
        success = self.connection_event.wait(timeout=CONNECT_TIMEOUT)
        if not success:
            if self.retry > CONNECT_RETRY_COUNT:
                logger.error(
                    f"Failed to connect to master {self.master_host}:{self.master_port}, after {CONNECT_RETRY_COUNT} retries"
                )
                raise ConnectionError()
            self.connect_to_master()
        self.connected = True
