Revert "Merge branch 'iterations_add_daterange_constraint' into 'master'"

What does this MR do?

Right now:

• package-and-qa is broken (because of !32335 (comment 349709076)).
• review-deploy is broken (#219198 (closed)).

This reverts !32335 (merged) which caused these issues.

Before reopening !32335 (merged) and merging it, we should make sure package-and-qa and review-deploy pass (meaning there's an omnibus-gitlab MR counterpart in addition to gitlab-org/charts/gitlab!1372 (merged)).

Closes #219198 (closed), #219213 (closed).
