> We blindly pick first component in a row, if no preferred client components 
> found
> As solution, we should check for healthy candidate, and check the case - that 
> first selected component could be not installed at all(i.e. not installed on 
> any host). This could be happened if first picked up component is a slave 
> with cardinality 0+
