Description

ElasticSearch can take some time to get ready for queries and actual activation code do not wait for it's readiness.

If a query is sent to ES right after activation there's a chance it's not ready and one gets the following error: "Failed to execute phase [query], all shards failed".

This error pops up quite often when using embedded ES in unit tests.

To mitigate this we should, on activation:

• ensure the Qi4j index is refreshed
• wait for ES yellow status (the primary shard is allocated but replicas may not be)
