Kibana multi-tenancy support

[poppelaars]

Describe the feature:

Multi-tenancy support for Kibana. Either through object replication or Kibana syncing or whatever term, or means, that would provide this.

Describe a specific use case for the feature:

Elasticsearch provides cross cluster search but Kibana can only connect to one Elasticsearch cluster. If I would like to create a single interface to search all of my data this is possible due to cross cluster search.

However, when I have multiple locations and want them to be self-supporting for example when using Kibana alerting, I would need to setup a Kibana instance for each location. Each instance could still be connected and configured to support the CCS so this would work fine. But from a user perspective you would like to give them a single interface with all of their queries, visualizations and dashboards.

As described I would like multiple locations to be self-supporting. In case of a network failure between data-centers or any other cause the internal data-center should still be functioning (alerting, queries, visualizations) without external support or resources.

Kibana does not support Cross Cluster Replication. In the current situation I would need to create a Kibana replicator that exports all objects from one Kibana instance to another Kibana instance to keep the Kibana instances in sync.
