Upgrade Log file size and count handling

[lovesh-ap]

the order of precedence and explanation for configuration variables affecting log rotation.

• If log_daily is true:

1. A log_limit_in_kbytes value greater than zero will result in a composite triggering policy, where logs will roll once per day or when the defined size is reached, retaining up to log_file_count files
2. A log_limit_in_kbytes value of zero will result in logs rolling once per day retaining up to log_file_count files

• If log_daily is false and log_limit_in_kbytes > 0, a sized based policy will be configured, where logs will roll when the defined size is reached, retaining up to log_file_count files

• If log_daily is false and log_limit_in_kbytes = 0, no log file rolling logic will be configured
