Resolve "Elasticsearch AutoRollingUpgrade is getting error"

General MR

Summary

This MR, though originally intended to "fix" the elastic upgrade job, is actually removing the job altogether. The job is unnecessary as the ECK operator (which this package depends on) already handles upgrade logic for ElasticSearch and Kibana instances deployed via its CRDs.

 Testing Steps:
 
 - Ensure all pods go to running (NOTE: this is especially important for the upgrade testing since Big Bang has an "auto rolling upgrade" job in place)
-- Log in to Elasticsearch [default credentials](https://repo1.dso.mil/big-bang/bigbang/-/blob/master/docs/guides/using-bigbang/default-credentials.md) to ensure that the Elasticsearch endpoint is available
 - Log in to Kibana with [default credentials](https://repo1.dso.mil/big-bang/bigbang/-/blob/master/docs/guides/using-bigbang/default-credentials.md), using the password in the `logging-ek-es-elastic-user` secret and username `elastic`
