Cannot create historian collection

[mathieu-rossignol]

At Helm install time, sometimes historian collection cannot be created when historian server starts, due to solr/zookeeper not yet ready:

Logs from historian server pod, after the startup.sh script which is in charge of creating the collection has already run:

Although the script waits for solr to be up, may be the condition is not ok to yet create a collection (should be investigated).

Workaround: after solr/zookeeper is stabilized, delete the historian pod which gets restarted by the replicaset, then the collection is created and the server starts.
