Adds 'all_tenants' search option in volumeprovider/cinder.py

When user create a docker volume with a pre-created cinder volume,
user can't see the docker volume if the pre-created cinder volume's
tenant is diffent to the tenant Fuxi use.
This patch adds 'all_tenants' option configurable.
With this, user can search cinder volumes over all tenant.
