[pbs-devel] [PATCH proxmox-backup 04/10] ui: Utils: add parse_datastore_worker_id

[Dominik Csapak <d.csapak@proxmox.com>]

to parse the datastore out of a worker_id
for this we need some regexes that are the same as in the backend

for now we only parse out the datastore, but we can extend this
in the future to parse relevant info (e.g. remote for syncs,
id/type for backups)
