implemented EvaluateAndAdjustConcurrency metrics decision maker

[ShocOne]

Change

EvaluateAndAdjustConcurrency evaluates the HTTP response from a server along with the request's response time
and adjusts the concurrency level of the system accordingly. It utilizes three monitoring functions:
MonitorRateLimitHeaders, MonitorServerResponseCodes, and MonitorResponseTimeVariability, each of which
provides feedback on different aspects of the response and system's current state. The function aggregates
feedback from these monitoring functions to make a decision on whether to scale up or scale down the concurrency.

The decision is based on a simple majority of suggestions: if more functions suggest scaling down (return -1),
it scales down; if more suggest scaling up (return 1), it scales up. This method centralizes concurrency control
decision-making, providing a systematic approach to managing request handling capacity based on real-time
operational metrics.
