> _Background_:
>   * The scope of this task is to provide a script that reads a dir structure for all configs. **For now only site.xml** since env files cannot be parsed, we might need to handle yaml files in later version.
>   * It produces a output of all the problems / conflicts found along with a configuration.json which can be directly incorporated in a cluster **blueprint**
> _Tasks_:
>   * Please find the attached patch with a partial script that you can start from (Really basic foundation patch).
>   * Assume that user has copied all the configs in a directory, example:  
> /tmp/my-master-configs/etc/hadoop/conf,  
> /tmp/my-master-configs/etc/hbase/conf,  
> /etc/my-slave-configs/hadoop/conf and so on. (There could be 5 core-site from
> different master / slave / client)
>   * Parse these files and merge them into a map of configs that can be exported to json based on following rules: 
>     * If propertyA is found in core-site1 and core-site2 with same value, add it to the map
>     * If propertyA is found in core-site1 only, add it to the map
>     * If propertyA is found in core-site1 and core-site2 with different value, add it to an output file with same name as the config-type, as a conflict.  
> Sample file (Choose appropriate formatting of choice) ::
>         
>                 core-site-conflicts.txt ::
>         || Conflicts ||
>         | propertyA  | <path-to-config-file> | value |
>         | propertyA  | <path-to-config-file> | value |
>         
>     * **Note**: Single run should generate all the conflicts, if no conflicts found generate the json file
>     * Provide ability to force output and also a verbose mode to log every step
