[xjia1]

• [x] Gerrit latest version is 3.8.2. They will release 3.9 soon.
• [x] Keycloak latest version is 22.0.5.
• [x] Redmine latest version is 5.0.6. Need to rebase https://github.com/naivesystems/redmine/tree/nsbox

Rebase doc: https://github.com/naivesystems/box/wiki/Redmine

I have already done the rebase for 5.0.6 this time. You will have to modify redmine/Containerfile to use it for testing.
