Interface & Factory implementation for VPD Parsers
This commit abstracts the implementation logic of different parser.
A parser factory is implemented to provide instance of required
parser based on the type of vpd file needed to be parsed.
The interface should be derived to implement any further parser logic
related to vpd.
Status: This does not add any new function, so basic testing of
VPD parsing, VPD tool and writes was performed.
