Datacenter moid should be a value not a tuple

[Yang Yu]

In edge_appliance_driver.py, there is a comma added when setting the datacenter moid, so the result is the value datacenter moid is changed to the tuple type, that is wrong.

 if datacenter_moid:
edge['datacenterMoid'] = datacenter_moid, ===> Should remove the ','
return edge
