arlakshm 7c699df654 Add support for bcmsh and bcmcmd utlitites in multi ASIC devices (#4926)
Signed-off-by: Arvindsrinivasan Lakshmi Narasimhan <arlakshm@microsoft.com>
This PR has changes to support accessing the bcmsh and bcmcmd utilities on multi ASIC devices
Changes done
- move the link of /var/run/sswsyncd from docker-syncd-brcm.mk to docker_image_ctl.j2
- update the bcmsh and bcmcmd scripts to take -n [ASIC_ID] as an argument on multi ASIC platforms
