No index information when host configured in elasticsearch_hosts is unreachable (but elastic cluster is not red) #3993

Jest now retries failed Elasticsearch requests a configurable number of times (default: 2) until it gives up. Unfortunately, the retry implementations in Apache Http Client via `HttpRequestRetryHandler` couldn't be used because they don't allow changing the request (or at least the request URI) between retries which is necessary to use all configured servers in the server pool. Fixes #3993

Expected Behavior
I configured
elasticsearch_hosts
with 8 elastic hosts:When 1 elastic node went offline (stoped elasticsearch for test purposes) graylog was unable to display the "indices" page and displayed a warning that I should check that the elastic cluster is reachable.
As the cluster was only in yellow state (and shortly after green) I expected graylog to be able to still display index information. During the whole time graylog was able to output logs and search them.
Current Behavior
An error message is displayed telling me to ensure the elastic cluster is reachable.
Possible Solution
As advised by Joschi on irc:
elasticsearch_hosts
elasticsearch_discovery_enabled
Steps to Reproduce (for bugs)
elasticsearch_hosts
