While Elasticsearch requires very little configuration, there are a number of
Reorganize configuring Elasticsearch docs This commit reorganizes some of the content in the configuring Elasticsearch section of the docs. The changes are: - move JVM options out of system configuration into configuring Elasticsearch - move JVM options to its own page of the docs - move configuring the heap to important Elasticsearch settings - move configuring the heap to its own page of the docs - move all important settings to individual pages in the docs - remove bootstrap.memory_lock from important settings, this is covered in the swap section of system configuration Relates #27755

Add temporary directory cleanup workarounds (#32615) On some Linux distributions tmpfiles.d cleans files and directories under /tmp if they haven't been accessed for 10 days. This can cause problems for ML as ML is currently the only component that uses the temp directory more than a few seconds after startup. If you didn't open an ML job for 10 days and then tried to open one then the temp directory would have been deleted. This commit prevents the problem occurring in the case of Elasticsearch being managed by systemd, as systemd private temp directories are not subject to periodic cleanup (by default). Additionally there are now some docs to warn people about the risk and suggest a manual mitigation for .tar.gz users.
