Macro info_in_release

macro_rules! info_in_release {
    ($($arg:tt)*) => { ... };
}

This is wrapper for info log.

In our CI tests, we frequently create and drop tables, and checkpoint in all barriers, which may cause many events. However, these events are not expected to be frequent in production usage, so we print an info log for every these events. But these events are frequent in CI, and produce many logs in CI, and we may want to downgrade the log level of these event log to debug. Therefore, we provide this macro to wrap the info log, which will produce info log when debug_assertions is not enabled, and debug log when debug_assertions is enabled.
