[PATCH proxmox v4 1/5] pbs-api-types: implement Hash and Borrow<str> for BackupArchiveName

[Jakob Klocker <j.klocker@proxmox.com>]

Sets of archive names are currently built as HashSet<String>, losing
the validation and type information BackupArchiveName provides.
Implementing Hash allows using BackupArchiveName directly as a set or
map key, and Borrow<str> keeps lookups by plain &str possible, e.g.
when matching file names read from a snapshot directory.
