SUMMARY

Dashboard supports nested tabs and charts. But user can add anchor in the request url, and dashboard will be landed with the component in the anchor. For example:
https://superset.d.musta.ch/superset/dashboard/homes/#TAB-DZy3k25d_ will open a specific tab.
https://superset.d.musta.ch/superset/dashboard/homes/#CHART-59WSceLod1 will open a specific chart.

This PR is to add the anchor component into dashboard perf log, so that we can see which tab/charts are more popular. This will help dashboard warm-up tasks.

TEST PLAN

CI and manual test.
