Description
Hello,
I've added refreshed state for snapshot, filesystem_snapshot, volume, and consistency_group to provide refresh capability for snapshots and thin clones.
A pending pull request for storops (emc-openstack/storops#375) needs merging and releasing before the related PR accepted.
Please review the modifications and feel free to ask if you have any questions.
Rationale
With the refresh capabilities added, one can easily update a test environment without a lengthy copy / backup-restore process.
