[Organize Code]Sync images of Gitlab CI templates between JiHu and upstream
In jh/ there is a directory which holds copies of Gitlab/Ci/Templates. The reason why we need the copies is because registry.gitlab.com is blocked in China - since it's on GCP - we have to manually upload the docker images to Tencent Cloud then modify corresponding templates to make sure they work in China.
Manual work is not sustainable, any CI template changes from upstream would cause errors in JiHu, and the only way we could do is to compare the differences and fix templates/rspec test by hand every single time.
The issue is raised to for us to discuss the way to eliminate manual work and sync images seamlessly between Jihu and upstream. This is also helpful for air-gapped instances since docker images will no longer be hard-coded in templates.
