This commit adds new code which supports the new buffer mgmt infra.
- Added new code to support buffers for T0 and T1 configs of S6100.
- Added new qos.json file to support qos on S6100.
- Changed the pg_profile_lookup.ini file to support xon_offset.
- Changed buffer.json.j2 file according to new buffer mgmt infra.
Unit tested by verifying the above changes by loading S6100 with the
configuration, checked the hardware for broadcom recommended settings
by running bcmcmd. Sent the unit test logs to Ying.
Checked the PG_RESET_OFFSET value which reflects the new xon_offset value of 2288
from the pg_profile_lookup.ini.

This commit adds new support for dynamic buffer configuration. The cable_length macro is
updated to return the cable length for server ports. Since the server ports are part of
VLAN MEMBERS, the macro loops through the VLAN MEMBER ports and returns the cable length
accordingly. If the port is not part of the SERVER port then it defaults to default cable
length. The new code in the macro will be executed only if the switch is ToRRouter
which is connected to the server on one side.
Tested the code by loading minigraph configuration on the switch which had configuration
for leaf-router as DEVICE NEIGHHOR and server ports in VLAN and ports which are not part of
either server or leaf router. The dynamically generated buffer.json and config_db.json file
had the cable_legnth updated accordingly for server ports with "5m" and leafrouter with "40m"
and unconnected port to default "300m". The redis database also reflects the buffer profile's
for 5m, 40m and 300m.

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.
