HDFS-16471. Make HDFS ls tool cross platform

[GauthamBanasandra]

Description of PR

The source files for hdfs_ls 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 this tool cross platform.

How was this patch tested?

hdfs_ls

I ran this tool locally with root as the parameter, where it lists the contents of the root directory -

./hdfs_ls /

I then ran it with the recursive option (-R) with root as the argument, where it lists all the files recursively from the root -

./hdfs_ls -R /

For code changes:

• Does the title or this PR starts with the corresponding JIRA issue id (e.g. 'HADOOP-17799. Your PR title ...')?
• Object storage: have the integration tests been executed and the endpoint declared according to the connector-specific documentation?
• If adding new dependencies to the code, are these dependencies licensed in a way that is compatible for inclusion under ASF 2.0?
• If applicable, have you updated the LICENSE, LICENSE-binary, NOTICE-binary files?
