Remove index on issues.relative_position

See merge request gitlab-org/gitlab!43991

This index is only on a single column, `relative_position`. However,
when we query issues by anything other than ID, we pretty much always do
that with a filter on `project_id`. (The exception is an admin user
viewing a dashboard, which is a rare case, and there aren't
instance-level boards anyway.)

We already have an index that's perfect for filtering by `project_id`
and ordering by `relative_position`, because it's on these columns:

    (project_id, relative_position, state_id, id DESC)

But sometimes the planner won't use it because of this index, which can
lead to poor query performance.

This commit adds support for using optimistic locking on the database
level when migrating a build trace chunk to a persistent store. It
allows us to safely migrate data to the object storage or database while
avoiding certain race conditions related to chunks migration.
