Get/set user-defined metadata for a storage object

object: A blob container, file share or ADLS filesystem object....: For the metadata setters, name-value pairs to set as metadata for a blob or file.blob, file: Optionally the name of an individual blob, file or directory within a container.snapshot, version: For the blob method of get_storage_metadata, optional snapshot and version identifiers. These should be datetime strings, in the format "yyyy-mm-ddTHH:MM:SS.SSSSSSSZ". Ignored if blob is omitted.isdir: For the file share method, whether the file argument is a file or directory. If omitted, get_storage_metadata will auto-detect the type; however this can be slow, so supply this argument if possible.keep_existing: For the metadata setters, whether to retain existing metadata information.get_storage_metadata returns a named list of metadata properties. If the blob or file argument is present, the properties will be for the blob/file specified. If this argument is omitted, the properties will be for the container itself.
set_storage_metadata returns the same list after setting the object's metadata, invisibly.
These methods let you get and set user-defined properties (metadata) for storage objects.
