Bug 2125499

This bug was initially created as a copy of Bug #2100154

I am copying this bug because: 

we need to have 8.8 and 9.2 in par


Sos report treats yum and dnf as separate commands, collecting 2 sets of information. Some of this is duplicates, while others don't know the 2 directories exist.

* sos_commands/yum should be a link to sos_commands/dnf

  This will put all the commands in one directory so engineers won't forget to look in both locations.

   # ls -l /usr/bin/yum
     lrwxrwxrwx. 1 root root 5 Mar 18 11:21 /usr/bin/yum -> dnf-3

* Instead of grabbing a specific package with: "dnf_--assumeno_list_installed_dnf", lets grab "dnf list --installed" and get a full listing of the installed packages. 

* remove "--assumeno" from all the commands. It's really not necessary as there is no "y/n" prompt from any of these commands:
