Skip testcases when shared nets are found in AutoAllocateNetworkTest

Shared nets is common configuration for the system, e.g., if we set
create_isolated_networks = False, we will create a shared net for
all testcases/tenants to use, which is specified by fixed_network_name.
So, when shared nets are found, we should skip the testcase instead of
raising an exception.
