[BUG] Conversion Error from Single Node to Cluster when user prompts to run backup

[rishagg01]

Describe the bug

For release 2.3.0, during internal testing for upgrade from single node lme to cluster, when user chooses to run run back up of single node lme prior to conversion to cluster, the script fails, right after back up.

To Reproduce

1. Set up a 3 node cluster with a windows client machine. Used the documentation for Release 2.3.0:
   https://github.com/cisagov/LME/blob/integrate-develop/testing/v2/installers/cluster_installer/README.md
   Follow the manual steps. Do not run Step 8, cluster install.

2. On the master, install single node LME from the LME main branch from LME Github.

3. On the windows client machine, added elastic agent, wazuh agent and Sysmon.

4. Then switched to integrate-devlop branch and created cluster inventory file.

5. Then ran the upgrade to cluster script: ./scripts/convert_to_cluster.sh --skip-inventory

This script fails when user chooses y to back up LME. The back up runs to completion but the conversion portion fails at kickoff after back up is completed, as shown in screenshot.

The playbook was trying to grab the indices when the services hadn't started up yet. We actually didn't need to start the services back up after the backup because we were just going to shut them down for the conversion. So we got the indices before it shut down for backup. Working now.
