[POC] SO Metadata events streams

[sebelga]

POC for the content management "metadata events".

Issue related: #9202

[sebelga]

Instead of having the home plugin knowing about the user_content plugin and do this import we probably want to put an extension point in place where plugins can add modifiers to the sample data before it is loaded.

In this case the user_content plugin would register a modifier in the home plugin to add the defaultUserContentAttributes.

[sebelga]

I am not sure why we have duplicate mappings definition with the server. This would probably need to be refactored to have a single mappings declaration

[sebelga]

Swap savedObjects.registerType with userContent.registerContent and we start gathering metadata information for this saved object type.

[sebelga]

This route is used for dev purpose. This logic should be called daily by a Cron Job to update the counters.

Saved Objects .kibana field count

Every field in each saved object type adds overhead to Elasticsearch. Kibana needs to keep the total field count below Elasticsearch's default limit of 1000 fields. Only specify field mappings for the fields you wish to search on or query. See https://www.elastic.co/guide/en/kibana/master/development-plugin-saved-objects.html#_mappings
