install_if does all of the bundling work even if the condition is false. That means it fetches the packages list from gems.contribsys.com before it even checks the condition. If BUNDLE_GEMS__CONTRIBSYS__COM isn't set it that fetch fails with an auth error.

This PR changes the
retry_incalculation for concurrency throttled jobs using the:schedulestrategy. The approach is to estimate when a throttled job will likely be runnable and schedule it for that time. This estimate is based on the current backlog size for the job group (estimated), the expected job runtime and the concurrency limit.This should reduce/eliminate unnecessary delays in job processing caused by the current "ignore throttled jobs for TTL seconds" approach while retaining the benefits of the schedule strategy.
PS: I changed the appraisals file because install_if does all of the bundling work regardless of whether the condition evaluates to true or false. In fact, it fetches the packages list from gems.contribsys.com before it even checks the condition. If BUNDLE_GEMS__CONTRIBSYS__COM isn't set that fetch failed with an auth error.
