integration_cleanup: Force testcase cleanup to always run

During testcase development on the integration side, if
namespaces are used or veth ports and an exception is raised.
The namespaces and veth ports are not properly cleanup up
because the run_finalize does not get executed.

This patch wraps the testing block in a try block where
a finally will ALWAYS execute the run_finalize thus
preventing the possiblity of leftover testing artifacts.
