Consider not supporting accessed_time and created_time Storage methods #83
Description
accessed_time and created_time are not supported by minio yet our storage class returns values from them by just returning the value of get_modified_time.
The Django documentation clearly states that these are supposed to raise NotImplementedError if not supported so we will do that.
Returns a datetime of the last modified/accessed/created time of the file. For storage systems unable to return the last modified time this will raise NotImplementedError.
- make it a setting to enable the less strict mode.
