backup list on an instance, shows backups owned by other tenants

[Saurabh Surana]

When we try to get backups list for an instance, it lists all the backups of that instance which are even owned by the other tenants.

curl -X GET -i http://10.0.0.1:8779/v1.0/<TenantID>/instances/<Instance ID>/backups

When it returns that list, the backups that are owned by other tenants are anyways not usable by regular users (regular user cannot delete the backups owned by other user or they cannot restore from such backups either, as regular user will not have access to remote user's swift account).

So such complete list should be returned only for the admin user and for regular users we should return the list of backups that are owned by them only.

    Restrict backup-list on instance to tenant

    Fixed backup-list on an instance, so that we show all available backups for
    the instance iff the user making the request is an admin. For a non-admin
    user, we return only the backups in his particular tenant.
