Dragonfly crashes at the next snapshot period if previous one was skipped

[safa-topal]

Describe the bug If dragonfly skips a snapshot period due to SAVE operation taking longer than the defined snapshot_cron (example: if save takes more than 10min when snapshot cron is set to every 10min)

To Reproduce Steps to reproduce the behavior:

1. Insert entries to DF (ideally GBs) and set the snapshot_cron to a relatively small value e.g: 1min
2. Ensure snapshotting takes more than 1min
3. See that process crashes if previous interval was skipped

Expected behavior Dragonfly must not crash.

Environment (please complete the following information): OS: Fedora 38 Kernel: 6.3.12-200.fc38.x86_64 Containerized?: toolbox Dragonfly Version: 1.14.5
