Description

The source files for hdfs_createSnapshot, hdfs_disallowSnapshot and hdfs_renameSnapshot uses getopt for parsing the command line arguments. getopt is available only on Linux and thus, isn't cross platform. We need to replace getopt with boost::program_options to make these tools cross platform.
