Review request for Ambari and Dmitro Lisnichenko.


Bugs: AMBARI-15650
    https://issues.apache.org/jira/browse/AMBARI-15650


Repository: ambari


Description
-------

There were tons of situations when we had only output of task failure, when a 
certain service failed to start/stop/restart, but couldn't get the logs of 
services.
Which makes fixing those bugs pretty problematic or even impossible if no 
reproduce is available.
This jira aims to output a short tail of service logs on start/stop failures, 
this should cover a big part of such a scenarios.
