Add Suppression Anomaly Rules in Advanced Settings (opensearch-projec…

…t#859)

This PR introduces suppression anomaly rules under the Advanced Settings section, enabling users to suppress anomalies based on the difference between expected and actual values, either as an absolute value or a relative percentage.

Testing:
* Added unit tests to verify the suppression rules functionality.
* Conducted manual end-to-end (e2e) tests to validate the implementation.
