Documentation update, health rules polishing

[jotak]

Description

• Rename IngressLatencyTrend => IngressHTTPLatencyTrend to distinguish with our other TCP latency
  • runbooks update: Netobserv: rename IngressLatencyTrend => IngressHTTPLatencyTrend openshift/runbooks#387
• Mark InstallDemoLoki as Unsupported
• Rename Alerts.md => HealthRules.md, and refresh its content; link to runbooks for details
• Regenerate asciidoc

[jotak]

@gwynnemonahan , for the downstream doc, here's the key things:

• Updated APIs: FlowCollector, FlowMetrics and the new FlowCollectorSlice
• Updated flow format reference: here
• I've updated the upstream doc on Alerts (now referenced to as Health Rules, since it's not only Alerts anymore); instead of rewriting a description for each of them, I just put a link to the runbooks, which contain all the details.
  • Note there are updates in the "metadata" section that should be replicated here
