Improve Logging for User Account Update Time Configuration in ShellBasedIdMapping Constructor

The original implementation of the ShellBasedIdMapping constructor lacks detailed logging about the configuration of the user account update time (usergroupid.update.millis). When this time is set to a value less than 1 minute, the system automatically adjusts it to the minimum of 1 minute without providing clear feedback to the user. This can lead to confusion and difficulty in troubleshooting if the user is unaware that their configuration was overridden. By adding detailed logs, we can ensure that users are informed about the exact configuration being applied, making it easier to diagnose potential issues related to configuration.
 
Expected Behavior:
When the ShellBasedIdMapping constructor is invoked, the system should log the user-configured update time for user accounts. If the update time is below the minimum threshold (1 minute), the system should log a warning indicating that the minimum value of 1 minute will be used instead.
 
How-to-Fix:
We propose to expose such a relationship by adding detailed logging statements to inform the user about the configuration status.
