Include the JSON Convert CLI tool `jc` in Red Hat Enterprise Linux (RHEL)

Issue

• Common command line tools like ps, multipath, systemd, subscription-manager, netstat, lsblk, free, ip, etc. have none or limited support for json/yaml output
• If you have to parse information from Linux commands, it is not always clear how to parse outputs of those commands correctly, and it usually requires some tweaking
• jc is used to JSONify the output of many command-line tools and file types for easier parsing in scripts
