qingstor: default --qingstor-upload-concurrency to 1 to work around bug

Browse Source 
If the upload concurrency is set > 1 then the hash becomes corrupted.
The upload is fine, and can be downloaded fine, however the hash is no
longer the md5sum of the object.  It is not known whether this is
rclone's fault or a bug at QingStor.
