Do not set_acls if store is not associated to glance node
In case of glance multiple stores (mostly for ceph) nova initiates
copy-image functionality if image, from which the sever is being
created, is not present in the referring ceph store. This can fail if
image location which is already present in image but not available for
that glance edge node. This scenario can only be reproducible
with EDGE deployment.
In order to fix this, if the store is defined on that glance node
then only call set_acls method, else ignore it.
Closes-Bug: #2073945
