[PATCH v2] storagevolume: Use default value for param 'name' when appropriate
The changelog from the previous patchset (v1) is: - Update the default name method when uploading a file. - Add a default name method for an unexpected operation based on the current time. - Rebase to the latest commit.

The parameter 'name' is only required when creating storage volumes with the parameter 'capacity' (i.e. an empty volume). When creating volumes with 'url' or 'file', the volume name should have a default value if 'name' is not specified. Use a default name when creating storage volumes from a file or from a URL. The default name will be the file's or the URL's basename. If an unknown volume creation method is used (i.e. if another method is added in the future and this function is not updated accordingly), the default name will be based on the current time.
