What I did
Handled buffer model changes gracefully
Why I did it
When config qos reload is given in platforms with dynamic buffer model, swss restart is required. However, if swss is not restarted the buffermgrd will stay in static model and will program the orchagent with 'size' field not set in buffer pool due to dynamic mode checks in jinja2 template. This will result in orchagent calling SAI without SAI_BUFFER_POOL_ATTR_SIZE which is mandatory attribute.
Since this results in a SAI create API failure, it will result in orchagent crash.
So when the mode is changed to dynamic, buffermgrd will not process any configurations when running in static mode.
How I verified it
Added UT. Manually verified that config qos reload doesn't crash.
Details if related
