##### ISSUE TYPE
- Feature Idea

##### COMPONENT NAME
yum/dnf module

##### ADDITIONAL INFORMATION
The value operators work currently in the yum/dnf modules
```
yum :
   name: "pkg >= 1"
   state: present
```

Yum/dnf will determine the version available and install it if it matches the comparison operator
