[pbs-devel] [PATCH proxmox-backup v2 3/6] api: admin s3: make store prefix for check command optional

[Christian Ebner]

The store prefix is not really required for basic checks and was non
optional since the s3 clients relies on it for object key expansion,
so it should not be forgotten on regular datastore operations.

So make it optional instead. Since this relaxes the api constraints,
it is not a breaking api change.
