Add a universal parser for the colon-separated grammar 'PROVIDER:VOLUME[:CONFIG][:K=V,K=V,…]' that backs --bind-volume on systemd-vmspawn (next), machinectl bind-volume, and the future nspawn + service-manager BindVolume= integrations. The 'config' field is opaque to shared code and interpreted per backend (vmspawn: a DiskType name, future nspawn: a mount path). The trailing key=value list is parsed into the io.systemd.StorageProvider .Acquire() parameters (template, create, read-only/ro, size/create-size and request-as), with values validated against the existing storage-util enums and validators. Provider/volume names are checked with storage_provider_name_is_valid() and storage_volume_name_is_valid(); the combined "<provider>:<volume>" string is also validated as string_is_safe so it is safe to use as a QEMU device id. Add a test-machine-util unit test covering the happy paths plus a handful of malformed inputs. Signed-off-by: Christian Brauner (Amutable) <brauner@kernel.org>
