ReloadConfigurationFile should Reset storage options 

Currently in Podman if we reset the CONTAINERS_STORAGE_CONF path, we get
the graph driver options from the original config file as well as the
options from the override path. This PR resets the storageconf to the
initial state when called multiple times.

Also if user sets STORAGE_OPTS="" then we should use it to override all
other storage options.
