[orchagent] Put port configuration to APPL_DB according to autoneg mode (sonic-net#1769)

*Before puting port related configuration to APPL_DB, check autoneg mode first. If autoneg mode is enabled, "speed" and "interface_type" will not be put into APPL_DB; if autoneg mode is disabled, "adv_speeds" and "adv_interface_types" will not be put into APPL_DB; else all configuration will be put to APPL_DB for backward compatible.
