I don't need snapshots for all members of a statefulset! One would be sufficient.

Describe the feature you'd like to have.
Restrict the snapshot creation to a single member of a statefulset. This would be useful e.g. for mongodb statefulsets where the whole cluster could be restored from a snapshot of one member.

What is the value to the end user? (why is it a priority?)
Safe space. Reduce the number of snapshots taken in a cluster.

How will we know we have a good solution? (acceptance criteria)
If the claimSelector has multiple matches a snapshot is created for only one of them.

Additional context
In a statefulset it's not so easy to assign a label to only a single member of the set - so that this label could be used as a matcher.

So I thought if one has a label that uniquely identifies the statefulset one could use that label for the claimSelector.
Then we would get a match for the pvc attached to each member of the statefulset. If we would have a variable just as
singlematch and if that is set to true the snapshot would be taken for the first matching pvc only.
