2024.2.1.0-b108: [BACKPORT 2024.2][YSQL] Rotate logs in connection manager
@vpatibandla-yb vpatibandla-yb tagged this 16 Dec 04:54 
Summary:
Added support to the log rollover mechanism with the below support
  - If the log size exceeds a certain threshold, the log would be rolled over.
  - If the log rotation interval is specified, then the log would be rolled over at the specified interval.
  - If neither the log max size nor the log retention period is specified, the logs get rolled over at the beginning of a new day at 12 AM.
  - Added the connection manager pid as the suffix to the file. Example log file format name is ysql-conn-mgr-2024-12-04_042819.log.509355 where 509355 is the pid.
  - Support to specify the log max size and the log retention period as gflags. The default behavior is to rollover the logs at the beginning of a new day.
  - Enabled async logging on connection manager and the logs are serialized based on the upstream odyssey changes.

`ysql_conn_mgr_log_max_size` - Specify the max log size in bytes supported as a tserver gflag.
`ysql_conn_mgr_log_rotate_interval` - Specify the log retention interval in seconds. If the interval is not specified, the log rollover happens at the beginning of each dat at 12 AM.
