[Mellanox] Backporting reboot cause to 201811 (#3198)
* backport new platform api to 201811, reboot cause part * install new platform api on host * 1. remove chassis's dependency on sonic_platform_daemon. 2. add some mellanox-specific hardware reboot causes. 3. fix typo in files/image_config/process-reboot-cause/process-reboot-cause. * 1. add dependency of sonic_platform for base image 2. handle the case of reboot cause file not found * adjust log message.
