  -----------
  [HWKMETRICS-199] initia support for virtual clock in REST API tests

H-Metrics will use the virtual clock when the system property
hawkular.metrics.use-virtual-clock is set to true. It will cause the
VirtualClockHandler to be deployed. It provides endpoints for fetching,
setting, and incrementing the clock.

There is still some work to do to make tests more repeatable. Tests still have
to spin for some short delay to allow time for task execution to complete. This
of course is problematic because there is no way to know how long to block. We
need additional endpoints that provide functionality that are used in other
tests. That is, tests essentially wait for notifications from the task
scheduler that it has finished work for a time slice.

  -----------
  [HWKMETRICS-199] add an endpoint to block until scheduler finishes work

There is a new endpoint to block for a specified duration. On the server side,
we subscribe to the task schedulers time slices observable which emits a
timestamp at the completion of each time slice. That is, a timestamp is emitted
when all of the work for the time slice is finished. A request like,

  GET /hawkulr/metrics/clock/wait?duration=5min

will block the request until the task scheduler has completed the work for five
time slices.
