When running batched background migrations, allow a small variance in
the `interval_elapsed?` check, to prevent issues where the cron skips a
job execution due to missing the next execution window by only several
seconds.

Without the variance, a job scheduled to run every 2 minutes will often
run closer to every 3 minutes in practice.

Before this feature flag was enabled, Workhorse would reject any
multipart filename that contained a slash (e.g. `dist/release.tar.gz`),
even though GitLab never used the path in determining whether to store
the file. With this feature flag enabled, Workhorse extracts the base
from this filename so this path is effectively ignored. This allows
uploads via the API to work as before the endpoint was accelerated by
Workhorse.

For batched migrations with short intervals between jobs, ensure a
minimum `ExclusiveLease` timeout value is always set, so the lease has
less chance of expiring before the job is finished.

Also increase the lease timeout for migrations with longer intervals.
