[Feature Request] allow breaking changes for MGMT SDK

[msyyc]

When I want to use detect_breaking_changes locally for MGMT SDK, I have to annotate the skip logic as following which is inconvenient:

azure-sdk-for-python/scripts/breaking_changes_checker/detect_breaking_changes.py

Lines 399 to 402 in 20e6f28

	if package_name not in RUN_BREAKING_CHANGES_PACKAGES and not any(bool(re.findall(p, package_name)) for p in RUN_BREAKING_CHANGES_PACKAGES):
	_LOGGER.info(f"{package_name} opted out of breaking changes checks. "
	f"See http://aka.ms/azsdk/breaking-changes-tool to opt-in.")
	exit(0)

So I make PR #36051 to allow breakings detection for all MGMT SDK. However, it seems that the breaking detection tool is adopted in release pipeline:
https://dev.azure.com/azure-sdk/internal/_build/results?buildId=3877372&view=logs&j=b70e5e73-bbb6-5567-0939-8415943fadb9&t=090c7790-4f5a-56e9-60dd-0909d5f779fb

To unblock release, I have to revert it in #36104.

I notice https://github.com/Azure/azure-sdk-for-python/blob/20e6f288aa94a712d1f9a9fd6f8adef3da15b4fe/scripts/breaking_changes_checker/README.md#ignore-a-reported-breaking-change declares how to suppress breakings but it needs add it package by package and item by item which cost much effort. I hope it could also support regex like RUN_BREAKING_CHANGES_PACKAGES so that we could suppress breaking warning for all languages.
In one word, I hope to use the tool to show breakings but don't hope it reports error in release pipeline.

Sounds like this is a repeat of #35988, will track this change there. Currently working on increasing the flexibility of the suppression mechanism which should make it easier for you to mark the common suppressions across packages. Let me know if you're looking for a different solution here.
