> Enhance the current File API to allow write another copy of the configuration file to a specified folder.
> ========
> Most config files are created using the File API. Therefore, if enhancing the File API to allow write another copy of the configuration file, then change could be smaller.
> For any component, if it has configuration files to be monitored, just created the following 2 variables in the params.py:
> 1. monitored_config_files_dir: specify where to duplicate the config files
> 2. monitored_config_files: a list of files to be monitored.
> e.g.
> monitored_config_files = ['/etc/zookeeper/conf/log4j.properties']
> monitored_config_files_dir = '/var/run/ambari-agent/zookeeper'
> Whenever the file in the monitored_config_files list is updated by the File API, a copy should be saved to the monitored_config_files_dir.
