Add multistore image option

This is an attempt to populate tempestconf with
multistore feature enabled if and only if multiple
stores are available.
In Rocky and Stein, Glance has added the ability to
configure multiple stores as an EXPERIMENTAL feature.
This feature is fully supported from the Train cycle.
