redmine: process changelogs every 10 minutes

Wrap the original entrypoint script with a custom one that also runs a
loop in the background, which periodically lets redmine fetch git
repositories. When repositories are fetched, redmine interpretes
"closes" etc. in commit messages to mark issues as resolved.

Closes: OS#5331
