[feature] Support custom refresh intervals for each group of metrics

[zuobiao-zhou]

What's changed?

close #2188

Support custom refresh intervals for each group of metrics. The specific implementation is as follows:

1. Construct a cycle of job refresh interval list based on the refresh intervals of each metric.
2. When the job dispatches, select metrics that are due for refresh to form priorMetrics.

@tomsun28 Hi, the strange problem mentioned here #2271 (comment) has been solved.
According to the previous code, for jobs with multiple collection metrics, the metrics.setCollectTime execution time for metrics with a higher priority is somewhat delayed. This causes them to be missed during the selection of expired metrics in the next cycle, resulting in updates occurring every two cycles. so I move metrics.setCollectTime in constructPriorMetrics.






Customize collect intervals have been tested and there are no problem.

👍👍thanks LGTM, test passed. Since this involves basic scheduling, and we are preparing a new version, can we merge this major feature after the 1.6.1 release (maybe end of this month)?

I agree, we need to make this feature more stable before releasing it.
