FOUR-20954: Monitor ETag Caching Performance

[eiresendez]

Issue & Reproduction Steps

This PR adds metric tests using K6 to validate the performance and stability of the implemented ETag caching middleware.

Solution

• Introduced K6 tests to measure ETag middleware efficiency:
  • Dynamic Endpoint Detection: Identifies endpoints where caching is not applicable.
  • Performance Test: Measures average response time for endpoints under load.
  • Long Duration Test: Evaluates response time stability and error rate during prolonged usage.
• Tests are located in tests/k6/etag/.

How to Test

Add an API token in tests/k6/etag/config.js and run the following command:

k6 run tests/k6/etag/detect-dynamic-endpoints.js
k6 run tests/k6/etag/performance-test.js
k6 run tests/k6/etag/long-duration-test.js
