+ post-syseeprom
+ Syseeprom information gathering tool for SONiC
+ This tool will be started during the start phase of pmon container, gathering syseeprom info and write to state DB.
+ It's an one-shot task since syseeprom info are static.
+ With this tool, show syseeprom CLI will be able to get data from state DB instead of access hw or cache.
