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

        Summary: [Herriot] Implement a functionality for getting proxy users definitions like
groups and hosts.  (was: [Herriot] Implement a functionality for building proxy users file
and proxy users list.)
    Description: 
Gridmix should require a proxy user's file for impersonating various jobs. So, implement couple
of methods for getting the proxy users list and a proxy users file (it's a combination of
proxy users and groups) based on cluster configuration.

The proxy users list should require for map reduce jobs and proxy users file should require
for gridmix jobs.

The following are methods signature,
public ProxyUserDefinitions getHadoopProxyUsers() - get the list of proxy users list based
on cluster configuration.

The following are methods signature,

public String getProxyUsersFile() - getting the proxy users file based on cluster configuration
information.
public String buildProxyUsersFile() - Build the proxy users file using the cluster configuration.
public ArraryList<String> getHadoopMultiUsersList() - get the list of proxy users list
based on cluster configuration.
