MINIO PY 7.x fixes

[networkjackbb]

I had to make the following changes to the minio.py data_backend to match up with changes in Minio API 6 => 7

• from minio.error import (InvalidResponseError)
• from minio.error import (InvalidResponseError)
• from minio.deleteobjects import DeleteObject

rm_many()

    try:

• for del_err in self.client.remove_objects(self.bucket_name, uids): try:
• delete_object_list = []
• for delete_uid in uids:
• delete_object_list.append(DeleteObject(delete_uid))
• for del_err in self.client.remove_objects(self.bucket_name, delete_object_list):

I forgot the minio.error changes. Removed BucketAlreadyOwnedByYou and BucketAlreadyExists from the minio.error import line.

i have an updated version of the the minio.py file that incorporates these changes and it seems to be working fine with no errors.
