Review request for Ambari, Jonathan Hurley and Vitalyi Brodetskyi.


Bugs: AMBARI-14538
    https://issues.apache.org/jira/browse/AMBARI-14538


Repository: ambari


Description
-------

Stale alerts should include the host name(s) associated with the alerts. As 
these are ambari-server alerts reporting status about alerts that are not run 
including the host names in the alert_text may be a valid option.

The following pattern should be used for this alert:
{code}
The following host(s) have alerts which have not run within their specified 
intervals: <hostname>[<alert_label_1> (<stale_time>), <alert_label_2> 
(<stale_time>)], <hostname-2> ...
{code}

For example:
{code}
The following host(s) have alerts which have not run within their specified 
intervals: c6401.ambari.apache.org[NodeManager Web UI (12m), NameNode Process 
(6m), DataNode Health (2h)], c6402.ambari.apache.org[Flume Agent (2d)]
{code}
