[pve-devel] [PATCH pve-storage] fix #6450: add file-checksum endpoint to storage API

[Nicolas Frey]

The storage API endpoint now supports an optional 'checksum' parameter.
If set, the checksum is calculated using one of the hashing algorithms
listed in the enum and returned in the 'checksum' return property.

Fixes: https://bugzilla.proxmox.com/show_bug.cgi?id=6450
