This commit updates the shared headroom value for z9100
T0 and T1 profile based on the ratio. The ratio is derived
from the 40G broadcom recommended XL Sheet.
Unit tested the above configuration by dumping the registers
for the shared headroom. The shared headroom values in registers
reflects the correct new values for both T1 and T0.

* First part of skipping not used port for qos configuration
* Use active ports only to set QoS parameters for 6100
* Add a test for qos.json.j2
* Add a test for Dell S6100 buffers.json template
* Update submodulre
This commit adds new code to support z9100 PFC T1 support with
broadcom recommended MMU settings for PFC feature.
Unit tested the setting by loading sonic-broadcom.bin and checking
the hardware for the values from the JSON file. Added the config.bcm
file th-z9100-32x100G.config.bcm to this folder and updated the
sai.profile file to point to hwsku directory. sai.profile now
points to /usr/share/sonic/hwsku/th-z9100-32x100G.config.bcm

This commit adds new code to support z9100 PFC T0 support with
broadcom recommended MMU settings for PFC feature.
Unit tested the setting by loading sonic-broadcom.bin and checking
the hardware for the values from the JSON file. The T0 configs supports
fan-out of 100G ports on Z9100. Added new config.bcm for fanout of 100G
ports and tested the fanout by sending traffic using bcmcmd, new config.bcm
file will be copied to /usr/share/sonic/hwsku/th-z9100-8x100-48x50G.config.bcm.
The sai.profile file is updated to point to hwsku directory.

* [device/dell] Added dynamic sai.profile generation
This commit addds new code for generating dynamic sai.profile file.
The sai.profile.j2 will generate the sai.profile dynamically based on
the topology. It will generate the sai.profile under /etc/sai.d/ directory
in syncd. Before syncd is started this J2 file will be run from the start.sh
file from /usr/bin/ directory. Since the sai.profile is dynamically generated
the old sai.profile file is not required so deleted the file for S6100.
It also address couple of more changes for port_config.ini support is added
for speed in the file which can be used later to find the port speed. Also
the buffer_default_t*.j2 file the ports should be from 0 to 64 changed.
Unit tested the code on S6100 for dynamic generation of sai.profile file for
both T0 and T1 and the file was created in /etc/sai.d/sai.profile
Similarly tested the sonic binary on S6000 to make sure that the sai.profile is
copied from the /usr/share/sonic/hwsku/sai.profile to /etc/sai.d/sai.profile.

This commit has the workaround for sai.profile to point to
config.bcm T0 profile. This fix will be reverted once the
sai.profile.j2 dynamically generates this file.

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.

1. "make target/sonic-broadcom.raw" will create the compressed dd'able image.
2. This will also update the grub config files (device/dell/*/nos_to_sonic_grub.cfg) with the image versions.
