## What changed? <!-- Describe what has changed in this PR --> Added dynamic configs to allow controlling the metrics breakdown based on task queue name, partition ID, and Build ID. Refactored all the places in the code that used these tags to consider the dc value. ## Why? <!-- Tell your future self why have you made these changes --> - Task Queue cardinality may be a problem for some self-hosted users. These configs allow to reduce cardinality. - The dynamic config is per task queue so it allows to turn it on for one or few task queues under investigation while disabled for everything else. - Simply excluding the tag value is not a good enough solution because the gauges such as backlog size or age will be mixed across task queues and become invalid. In this change, I disable the gauge completely if the configs do not allow necessary breakdown. ## How did you test it? <!-- How have you verified this change? Tested locally? Added a unit test? Checked in staging env? --> Added few unit tests. ## Potential risks <!-- Assuming the worst case, what can be broken when deploying this change to production? --> ## Documentation <!-- Have you made sure this change doesn't falsify anything currently stated in `docs/`? If significant new behavior is added, have you described that in `docs/`? --> ## Is hotfix candidate? <!-- Is this PR a hotfix candidate or does it require a notification to be sent to the broader community? (Yes/No) -->
