…ic-net#12894)

Why I did it
The user framework module complies with s3ip sysfs specification

How I did it
1、 create a s3ip_sysfs service
2、 the s3ip_sysfs service call the “s3ip_sysfs_tool.sh” to install kernel module and run s3ip_load.py
3、 s3ip_load.py will parse the s3ip_sysfs_conf.json configuration file and create /sys_switch/ directory

How to verify it
A demo driver base on this framework will display the sysfs node wich conform to the s3ip sysfs specification
