Make Elasticsearch highly available in an independant app #419
Description
Feature Request
Is your feature request related to a problem or unsupported use case? Please describe.
Apps that need Elasticsearch include their own dc to deploy Elasticsearch but we are facing limitation:
- we want to benefit from highly available clusters
- we sometimes need to share the same Elasticsearch between different applications
Describe the solution you'd like
Add an independant Elasticsearch app with a configurable high availability cluster.
The app should not use blue/green deployments but rolling update. While doing the rolling update, the deployment should wait until each node is fully synchronized in the cluster before continuing with the next node.
After this is done, modify existing apps to make use of this HA Elasticsearch

I have no experience with ES clusters, but what would be the expected behavior if we upgrade the ES release with a rolling update, i.e. a cluster (pods) with mixed ES versions?
