The measurement timescales associated with domain::Tags::FunctionsOfTime.
We group measurement timescales by the control_system::protocols::Measurement that their corresponding control systems use. This is because one measurement may be used to update many functions of time. Each group of functions of time associated with a particular measurement has a corresponding timescale here, represented as PiecewisePolynomial<0> with a single entry. That single entry is the minimum of all control_system::calculate_measurement_timescales for every control system in that group.
The name of a measurement timescale is calculated using control_system::system_to_combined_names for every group of control systems with the same measurement.
If all control systems that use the same measurement aren't active, then the measurement timescale and expiration time are std::numeric_limits<double>::infinity().
