##### SUMMARY
`ansible-base collection list` doesn't show the packages installed by the new `ansible` package

As a workaround, you need to do:

```
COLLECTION_INSTALL=$(python -c 'import ansible, os.path ; print("%s/../ansible_collections" % os.path.dirname(ansible.__file__))')
ansible-galaxy collection list -p "$COLLECTION_INSTALL"
```
