Unconditionally refresh storage options from config

Browse Source 
Due to our unconditionally setting some storage options, we
are not always reading storage options from storage.conf. This
can lead to some fields in the storage config (most notably extra
storage options) being ignored, despite being set in
storage.conf.

Resolve this by unconditionally refreshing our storage config
from storage.conf (this was previously only done for rootless
Podman)

Fixes #2217
