Title: Make module output more consistent wrt. changed/failed

- Make sure exit_json() always returns a changed= value
- Modify the yum module to not return failed=False
- Modify install() and latest() similar to remove() in yum module
- Make sure yum rc= value reflects loop (similar to how we fixed remove())
