-----------------------------------------

Hi [~sunilg] & [~wangda], As discussed i have converted this jira into a umbrella, created
 a branch in git and created some initial tasks as jiras & have uploaded some initial
WIP patches for these jira's. Only pending tasks is to update the documentation based on our
discussions for this feature, will update them by tomorrow.
Thanks for the constant push and motivation, will continuously work on it and get it to closure!

> Specify only one label for each node (IAW, partition a cluster) is a way to determinate
how resources of a special set of nodes could be shared by a group of entities (like teams,
departments, etc.). Partitions of a cluster has following characteristics:
> - Cluster divided to several disjoint sub clusters.
> - ACL/priority can apply on partition (Only market team / marke team has priority to
use the partition).
> - Percentage of capacities can apply on partition (Market team has 40% minimum capacity
and Dev team has 60% of minimum capacity of the partition).
> Attributes are orthogonal to partition, they’re describing features of node’s hardware/software
just for affinity. Some example of attributes:
> - glibc version
> - JDK version
> - Type of CPU (x86_64/i686)
> - Type of OS (windows, linux, etc.)
> With this, application can be able to ask for resource has (glibc.version >= 2.20
&& JDK.version >= 8u20 && x86_64).
