Apply A2HA formatMsgNoLookups Config

gistfile1.txt

The following instructions should be run from any Elasticsearch node in the A2HA Cluster. 

It only needs to be done once and will automatically be applied to all the ES nodes in the cluster.

1. Get the current ES Configs

    ```
    source /hab/sup/default/SystemdEnvironmentFile.sh
    automate-backend-ctl applied --svc=automate-backend-elasticsearch | tail -n +2 > es_config.toml
    ```
    
2. Add the `es_java_opts` config, if there is already a `[runtime]` section add the `es_java_opts` config to that section

    ```
    [runtime]
      es_java_opts = "${ES_JAVA_HEAP} -Dlog4j2.formatMsgNoLookups=true" 
    ```

3. Apply the config and wait for ES to go green

    ```
    hab config apply automate-backend-elasticsearch.default $(date '+%s') es_config.toml
    journalctl -u hab-sup -f | grep 'automate-backend-elasticsearch'
    ```
    
4. Check that the new config was applied correctly

    ```
    ps -aef | grep java | grep formatMsgNoLookups=true
    ```
