smoketest: add shim for every test to re-use common tasts

Currently every smoketest does the setup and destruction of the configsession
on its own durin setUp(). This creates a lot of overhead and one configsession
should be re-used during execution of every smoketest script.

In addiion a test that failed will leaf the system in an unconsistent state.
For this reason before the test is executed we will save the running config
to /tmp and the will re-load the config after the test has passed, always
ensuring a clean environment for the next test.
