Clean-up Tempest test networks with project_id

Recently, Tempest test cases were added to test the creation
of networks with project_id. These test cases call the Tempest
network client directly. As a consequence, the test networks
are not cleaned-up after test execution.

This patchset adds a utility method to handle the creation of
networks with project_id that sets them up for deletion at the
end of the test
