Change config-service-test ns to match production code

We changed the namespace heirarchy for the configuration stuff at
some point in the past, but didn't change the namespace of the
config tests accordingly.
Add testutils macros for instantiating apps

This commit adds `with-app-*` macros that correspond to all of the
`bootstrap-services-with-*` functions in the bootstrap testutils.
These new macros handle the prevention of registration of jvm
shutdown hooks, and also ensure that the app's `stop` function
is called after the test is complete.
Add try/finally blocks to new bootstrap macros
Update KS dep to 0.5.3
