[RFE] Show failed commands from `sos_reports/sos.json`

[pafernanr]

It could be useful to show the commands that failed during the sosreport creation. If I am not wrong failed ones can be extracted from sos_reports/sos.json.

• This is a snippet:

        "alternatives",
        {
            "commands": [
                {
                    "name": "alternatives --list",
                    "return_code": 0,
                    "href": "../sos_commands/alternatives/alternatives_--list"
                },

• I mean use the return_code and href fields and show non zero return_code commands. E.g:

plugin_name	command	file	error_msg
alternatives	alternatives --list	../sos_commands/alternatives/alternatives_--list	{{error msg on the file}}

• error_msg could be truncated if too long.

@jjansky1 Do you know if "return_code" is accurate for this purpose?

[jjansky1]

@pafernanr return_code should be accurate for this purpose, but might be valuable to combine it with os.path.exists('example.txt'):, but will keep the decision on you.
