Such nodes in config are useful as a nodes with default values, that can be overwritten from ZooKeeper/env. So after this patch the following is valid, and is interpreted as default value 86400, and can be overwritten via env: ```xml <asynchronous_metrics_update_period_s replace="1" from_env="CH_ASYNCHRONOUS_METRICS_UPDATE_PERIOD_S">86400</asynchronous_metrics_update_period_s> ``` While the following is not: ```xml <asynchronous_metrics_update_period_s from_env="CH_ASYNCHRONOUS_METRICS_UPDATE_PERIOD_S">86400</asynchronous_metrics_update_period_s> ``` Signed-off-by: Azat Khuzhin <a.khuzhin@semrush.com>
