From: sugeshch <sugesh.chand...@intel.com>
This patch introduces two new files for exposing the chassis sysinfo to the CMS.
The new context named 'sysinfo_ctx' is also proposed in this patch to keep
track of the chassis information. The Controller on a chassis uses the functions
in this patch for populating the host information in OVN Southbound DB.
