Add throughput timer configuration (#5363)
The new "timers" section describes configuration for different timers.
Specifically, in the "throughput" section, it is possible to disable the
throughput timer (enabled by default). This allows to avoid the
performance degradation whenever the throughput measurement is not
needed, for example in production environment.
No device synchronize() is invoked when "synchronized" is set to False
(default is True). This allows to produce approximate throughput
measurements with minimal performance penalty.
