Does that mean PG 2 and 6 will be used as lossless PG? In that case BUFFER_PG|<port>|2, BUFFER_PG|<port>|6 need to be configured. But traditional buffer manager supports 3-4 only. This also needs to be updated
#define LOSSLESS_PGS "3-4"
string buffer_pg_key = port + m_cfgBufferPgTable.getTableNameSeparator() + LOSSLESS_PGS;

What I did
This PR is to update db_migrator to support pfcwd_sw_enable.
Currently, table pfc_enable is to specify on which queue to enable PFC and pfc watchdog. As we are going to add two extra lossless queues on which on watchdog is enable(HLD sonic-net/SONiC#950), a new field is required to specify on which queue to enable PFC watchdog. That is pfcwd_sw_enable.

Field	                 Description
pfc_enable	        Specify on which queues to enable PFC
pfcwd_sw_enable	Specify on which queues to enable software PFC watchdog
HLD DSCP remapping

Change in orchagent Update orchagent to support new field pfcwd_sw_enable

How I did it
Update db_migrator.

How to verify it
Verified by UT
Verified by copying the updated db_migrator.py to a SONiC box and run db_migrator.py -o migrate

How I did it
Update the buffers.json.j2 template and buffers_config.j2 template to generate new BUFFER_QUEUE table.

For T1 devices, queue 2 and queue 6 are set as lossless queues on T0 facing ports.
