PR Checklist

PR Structure

  • This PR has reasonably narrow scope (if not, break it down into smaller PRs).
  • This PR avoids mixing refactoring changes with feature changes (split into two PRs
    otherwise).
  • This PR's title starts with name of package that is most changed in the PR, ex.
    services/friendbot, or all or doc if the changes are broad or impact many
    packages.

Thoroughness

  • This PR adds tests for the most critical parts of the new functionality or fixes.
  • I've updated any docs (developer docs, .md
    files, etc... affected by this change). Take a look in the docs folder for a given service,
    like this one.

Release planning

  • I've updated the relevant CHANGELOG (here for Horizon) if
    needed with deprecations, added features, breaking changes, and DB schema changes.
  • I've decided if this PR requires a new major/minor version according to
    semver, or if it's mainly a patch change. The PR is targeted at the next
    release branch if it's not a patch change.

What

Wrap reap processing in a DB transaction.

Why

When checking #3711 I realized that since #3567 reap process can be stopped in a middle which can result in just a part of ledger data reaped causing issues like #3751.

Known limitations

It's likely that reap won't finish because of #3567. We should probably move it outside of global Tick (#613).
