Automatically enable multiple MR assignees feature flag
What does this MR do?
Schedules a background migration that checks whether
multiple_merge_request_assignees
feature flag needs to
be enabled, otherwise it'll be rescheduled.
The rule for enabling it is that
every PopulateMergeRequestAssigneesTable
background job
cannot be still running, or being retried or dead.
If there are any enqueued jobs in the state above, the
"checker" (MergeRequestAssigneesMigrationProgressCheck
) will
be rescheduled for 3 hours ahead.
This MR doesn't depend on the feature code MR https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/10161, given that the population migration MR was already merged (https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/26496). If the feature flag gets enabled automatically, that's fine, because the feature code is not there yet and we can disable it if we want. That's mainly needed for self-hosted instances.
