[Monitoring] Update monitoring template versions

[axw]

Update monitoring template versions to 7.12.0, to ensure they are replaced on upgrade.

The "local" (default) monitoring exporter checks the version before replacing the template:

elasticsearch/x-pack/plugin/monitoring/src/main/java/org/elasticsearch/xpack/monitoring/exporter/local/LocalExporter.java

Lines 365 to 377 in 1256558

	// Check that each required template exists, installing it if needed
	final List<String> missingTemplates = Arrays.stream(MonitoringTemplateUtils.TEMPLATE_IDS)
	.filter(id -> hasTemplate(clusterState, templateName(id)) == false)
	.collect(Collectors.toList());
	if (missingTemplates.isEmpty() == false) {
	logger.debug((Supplier<?>) () -> new ParameterizedMessage("template {} not found", missingTemplates));
	for (String templateId : missingTemplates) {
	final String templateName = MonitoringTemplateUtils.templateName(templateId);
	asyncActions.add(() -> putTemplate(templateName, MonitoringTemplateUtils.loadTemplate(templateId),
	new ResponseActionListener<>("template", templateName, pendingResponses)));
	}
	}

I made a change to .monitoring_beats in #65997, which landed in 7.11.0, but did not update the template version. On master, the "last updated version" is 7.0.0, and on 7.x it is 7.0.1. There have been several other template changes since 7.0.1. IIANM, with rolling upgrades, monitoring templates would not have been updated since 7.0.1.

@chrisronline not sure if you can review this or not. If not then I'll try and hunt down someone else who can.

cc @jakelandis Do we need to bump this version every time we make mapping changes?

Do we need to bump this version every time we make mapping changes?

@chrisronline - yes

@axw - if you are backporting this to 7.12, can you adjust the version here to 7.12 ? It shouldn't make a technical difference, but I can imagine someone looking a support diagnostic and scratching their head why on 7.11 the mappings are not installed. Also maybe a comment in the code that source code was updated in 7.11 but not applied until 7.12 and link to this issue ?

Thanks @jakelandis, I've updated the version as suggested.

@elasticmachine update branch
(looks like the test failure has recently been fixed/muted)

[jakelandis]

LGTM.

@axw - lmk if you bump into any issues merging or backporting.

Thanks @jakelandis! All done.
