Marks the specified blob or snapshot for deletion.
The blob is later deleted during garbage collection.

Note that in order to delete a blob, you must delete all of its
snapshots. You can delete both at the same time with the Delete
Blob operation.

:param str container_name:
    Name of existing container.
:param str blob_name:
    Name of existing blob.
:param str snapshot:
    The snapshot parameter is an opaque DateTime value that,
    when present, specifies the blob snapshot to delete.
:param str lease_id:
    Required if the blob has an active lease.
:param delete_snapshots:
    Required if the blob has associated snapshots.
:type delete_snapshots: 
    One of the values listed in the :class:`~azure.storage.blob.models.DeleteSnapshot` enum.
:param datetime if_modified_since:
    A DateTime value. Azure expects the date value passed in to be UTC.
    If timezone is included, any non-UTC datetimes will be converted to UTC.
    If a date is passed in without timezone info, it is assumed to be UTC. 
    Specify this header to perform the operation only
    if the resource has been modified since the specified time.
:param datetime if_unmodified_since:
    A DateTime value. Azure expects the date value passed in to be UTC.
    If timezone is included, any non-UTC datetimes will be converted to UTC.
    If a date is passed in without timezone info, it is assumed to be UTC.
    Specify this header to perform the operation only if
    the resource has not been modified since the specified date/time.
:param str if_match:
    An ETag value, or the wildcard character (*). Specify this header to perform
    the operation only if the resource's ETag matches the value specified.
:param str if_none_match:
    An ETag value, or the wildcard character (*). Specify this header
    to perform the operation only if the resource's ETag does not match
    the value specified. Specify the wildcard character (*) to perform
    the operation only if the resource does not exist, and fail the
    operation if it does exist.
:param int timeout:
    The timeout parameter is expressed in seconds.
