Routed sub-interface naming convention

Linux kernel has a limitation of 15 character interface name size, modify the sub interface naming convention to keep it in short format (e.g. Eth100.1234, or Po100.1234). This naming change for subinterfaces will kept it uniform across the entire SONiC subsystem (config, show, and in all dbs) for the subinterfaces. DB migrator scripts are enhanced for the name conversion during the upgrade.
