On MX304 platform, 'set system syslog file messages pfe any' configuration needs to be enabled by default in order to stream all FPC logs to RE(/var/log/messages).

MX304 FPC does not have Hard Disk, so it cannot store any FPC side logs on its own. By default only FPC(Flexible PIC Concentrators) ERROR logs are automatically streamed to RE(Routing Engine) side, while not all other logs. As a result, we might not have sufficient logs to analyze if any critical issue happens at FPC side or FPC gets rebooted.

PR1761073 added 'set system syslog file messages pfe any' configuration by default, so that all FPC side logs to be streamed to RE side (/var/log/messages) where Hard Disk is present. It can help to debug the FPC side issue whenever required.
