Added "status subscription" and "rerun" test.

We now have a regression test for the option to
check for the number of subscriptions.

Also, we check the different options available for
the "rerun" commmand.

Drop version numbers from test configs.

As these version numbers make no sense what so ever in the Bareos
world we just drop them from the regression configs.
