1. Enable volumeSnapshot quota depending on the volumeSnapshotClasses
2. The customer wants to define the number of snapshot depending on the volumeSnapshotClasses
3.
Currently is possible to create a custom resource quota regarding snapshots in OCP as we can see in the following KCS [1]. But it is not possible to define the number of snapshot depending on the volumeSnapshotClasses.

We would like to create a new RFE in order to define this kind of flexibility when creating resource limits. So, the main idea instead of computing the number of snapshots would be:

• To be able to allow X number of snapshots for RBD volumes.
• To be able to allow Y number of snapshots for CephFS volumes.

Something similar as it is possible to do using storage quotas where we can specify different quotas depending on the storage class used:

apiVersion: v1
kind: ResourceQuota
metadata:
name: testing-quota
namespace: testing-quota
spec:
hard:
ocs-storagecluster-ceph-rbd.storageclass.storage.k8s.io/persistentvolumeclaims: "2"
ocs-storagecluster-cephfs.storageclass.storage.k8s.io/persistentvolumeclaims: "5"
