This commit adds new support for dynamic buffer configuation. Adding pg_profile lookup table for supporting the buffer profile using cable length and port speed. Lookup table entries are calculated based on formula for different cable length and speed. The 50G entries needs to be updated once again as we are waiting for the interface sublayer MAC delay values. Additionally fixed some issues in the buffers.json.j2 file.
