    OODT-945 Rework OODT configuration to make use of Zookeeper for distributed configuration
management (GSoC 2017)

    This PR includes the Distributed Configuration Management implementation for OODT [OODT-945]
along with the distributed configuration publishing CLI [OODT-952].
    
    Explanation on the design of this feature is available at [Rework OODT configuration to
make use of Zookeeper for distributed configuration management](https://cwiki.apache.org/confluence/display/OODT/Rework+OODT+configuration+to+make+use+of+Zookeeper+for+distributed+configuration+management).
    
    User documentation on how to use this distributed configuration management feature is
available at [OODT Distributed Configuration Management](https://cwiki.apache.org/confluence/display/OODT/OODT+Distributed+Configuration+Management)
    
    Corresponding GSoC project proposal is available at [https://cwiki.apache.org/confluence/display/OODT/Proposal](https://cwiki.apache.org/confluence/display/OODT/Proposal)
    
    **Since this is the first glance of the distributed configuration management feature,
there can be bugs and improvements required to be addressed. Please review this PR and provide
me with your kind feedback so that I can improve on that.**
    
    Thank you!

> OODT is made up of a number of different components, each of which have their own set
of configuration files and locations. This is complex to manage and causes additional problems
when the platform requires distribution across servers or geographically.
> To combat this we are proposing that we migrate the OODT configuration to an opional
Zookeeper module that would allow users to commission a zookeeper cluster and register the
various OODT components against it, which will allow the zookeeper cluster to maintain the
state of the various OODT components regardless of scale.
