Elasticsearch: Improve logging in cluster wait

Browse Source 
The cluster wait function can sometimes receive an invalid response,
and this would "pass" the status check condition. This change
prints the response to make it more clear what occured, and changes
the condition to explicitly wait for a "yellow" or "green" status.
