Hi [~sunilg],

          Just had a overview and the patch seems to be fine, but one query i 
had was to how are we supporting Boolean type attributes ? i.e. we are 
currently supporting EQ( =)  and NE ( != ) only but during requirement 
discussion there were lot of use cases(from Microsoft) where in they wanted to 
use exists not exists kind of  operation instead of value  based comparison. I 
think this might pop up during merge. Thoughts?

> Scheduler should accept nodes which doesnt have an attribute when 
> NodeAttributeType.NE is used
