[jfagunde]

Reason for Change: Speed up L1 tests

Summary of Changes:

• Modify run.sh to print list of slow tests that take longer than 1s
• Make AampCurlDownloader delay between 502 retries configurable
• Modify various L1 tests to make them quicker

Test Procedure: L1 tests should pass and slow tests printed

Priority: P2

Risks: Low

Pull request overview

Speeds up the AAMP L1 unit-test workflow by shortening several long waits/timeouts, adding reporting for slow-running tests, and making the 502-retry backoff configurable in the curl downloader.

Changes:

• Add ctest JUnit output + a helper script to print tests exceeding a 1s duration threshold.
• Add iDownload502RetryWaitMs to curl download config and use it for 502 retry delays (tests can set it to 0 to run faster).
• Reduce waits/timeouts in a few L1 tests to shorten suite runtime.
