    Minor improvements in Cassandra shutdown and startup logs
    
    To improve a DBA experience the following log messages would be nice to add/adjust:
    on shutdown: an explicit message at the end of Cassandra shutdown
    on startup:
    - print the time spent to load prepared statements
    - print the time spent to load repair session information and the number of loaded session records
    - print the time spent to apply commit log
