Remove unused context parameter from cinder methods

[Abhijeet Malawade]

In cinder there are many methods which are not using context parameter at all.

ex.-
1. '_translate_snapshot_summary_view' method: https://github.com/openstack/cinder/blob/master/cinder/api/v2/snapshots.py#L44
2. 'service_version' and 'service_config' methods:
https://github.com/openstack/cinder/blob/master/cinder/manager.py#L106
3. '_add_volume_mig_status_attribute' method:
https://github.com/openstack/cinder/blob/master/cinder/api/contrib/volume_mig_status_attribute.py#L25
4. '_add_volume_tenant_attribute' method:
https://github.com/openstack/cinder/blob/master/cinder/api/contrib/volume_tenant_attribute.py#L25
5. '_add_replication_attributes' method:
https://github.com/openstack/cinder/blob/master/cinder/api/contrib/volume_replication.py#L42

So the context parameter should be removed from all of these Methods.
