Gitlab-shell request /api/v4/internal/shellhorse/git_audit_event, it depends on:

• gitaly!5848 (merged)
• gitlab!123486 (merged)

Because request git-audit-event and request gitaly are handled by different systems (one is rails-web, another is Gitaly), so it's hard to guarantee that both requests will succeed or fail at the same time, we just ignore the git audit event error and just log an error log，like:
