UserID is different with the image built by Jenkins if we build docker-sonic-mgmt in sonicbld pool.
So we build this image in sonictest pool. There is a sonictmp user with UserID 1001.
This will make docker image same as the image built in Jenkins
Add 3 pipeline files:
- pipeline for build docker image sonic-slave-[buster|jessie|stretch] for amd64/armhf/arm64, and push to ACR(sonicdev-microsoft.com)
- pipeline for build docker image sonic-mgmt, and push to ACR
- pipeline for cleaning dpkg cache which are created more than 30 days.
