VPD Tool: Write keyword command line interface
This commit has the command line interface
for writeKeyword option in the VPD tool.
--help option will provide the user - the argument format
for writeKeyword option.
Note:
The application "vpd-manager" acts as the backend for the keyword updation.
The vpd-manager executable should run in the background while testing in simics.
The commits which points to the vpd-manager backend application are,
