With the addition of a second tool `bench::ParameterRange`,
the setup of the test-context for measurement became confusing,
since the original scheme was mostly oriented towards the
''breaking point search.''
On close investigation, I discovered several redundancies, and
moreover, it seems questionable to generate an ''adapted-schedule''
for the Parameter-Range measurement method, which aims at overloading
the scheduler and watch the time to resolve such a load peak.
The solution entertained here is to move most of the schedule-ctx setup
into the base implementation, which is typically just inherited by the
actual testcase setup. This allows to leave the decision whether to build
an adapted schedule to the actual tool. So `bench::BreakingPoint` can
always setup the adapted schedule with a specific stress-factor,
while `bench::ParameterRange` by default does nothing in this
respect, and thus the `ScheduleCtx` will provide a default schedule
with the configured level-duration (and the default for this is
lowered to 200µs here).
In a similar vein, calculation of result data points from the raw measurement
is moved over into the actual test setup, thereby gaining flexibility.
