Log partial VSP deletion

Log partial VSP deletion

Adds entries to the VSP activity log identifying the VSP versions
deleted from the MinIO client, and also if the deletion was fully
complete.
If the VSP deletion from the database fails, there will be registry
of what happened with the MinIO deletion.
Do some refactor in the VendorSoftwareProductsImpl in relation to the
VSP deletion flow and responses.
