Sub-task 2: Add support for the “HitRate” Collector mode
A recent update of the Collector, and the corresponding control library, has added support for a new mode called “HitRate”. In this mode, every measurement taken contains the number of actions performed by the remote server during the measured time period, and how many of them were successful.
See the documentation of the ext_tools library for details.
When verifying the results, the threshold parameter should be used to indicate the smallest allowed “hit percentage” (i.e. failures per 100 actions performed). Any measurement with a “hit percentage” below the threshold should be considered a failure.
When presenting hit rates as a percentage, please use two decimal points, e.g. "92.14"
