Review request for Ambari, Alexandr Antonenko, Jaimin Jetly, Oleg Nechiporenko, 
Richard Zang, Srimanth Gunturi, Xi Wang, and Yusaku Sako.

Bugs: AMBARI-15519

Repository: ambari


On the cluster where some nodes are in the maintenance mode Add Service Wizard 
doesn't track this.
So, user may select host in the maintenance mode to install some master 
component. And this component won't be installed (only record in the DB will be 
created for it).
Another situation:
there is some cluster where all nodes are in the maintenance mode. In this case 
ASW is almost useless. Because all new components won't be installed while it 

ASW should track hosts in the maintenance mode and warn user about adding 
components on them (Steps "Assign Masters", "Assign Slaves and Clients").
