Add a mechanism for server-side tests to declare which of their
parameters is the Host object they run on. Also adds code to the
server test execution to automatically call Host.log_kernel before
each of those tests, so that we can ensure that the kernel a
single-machine server test is running on is always captured.

Risk: Low
Visibility: Adds semi-automatic kernel logging for server tests
