[ISSUE-176] allow reset-application-fixture to get bootsrap.servers from app-config

[7vs]

Issue #176 was already fixed by #179 although the fix was not backed by a unit test. @7vs and I (@cddr) had already begun working on this when @kidpollo submitted #179 but figured we'd continue as this PR back-fills a unit-test for the feature and also adds the ability for the user of the fixture to supply optional parameters, and an optional reset-fn which allows the unit test to check that the error case is handled with an informative exception (the StreamsResetter quite often fails in a dev environment when the state can easily become inconsistent but the error message usually contains enough information about what to do to resolve the situation.
