Explore adding table ids tags to some metrics

**Is your feature request related to a problem? Please describe.**

The monitor currently has a custom metrics system. This custom system in the monitor tracks certain metrics per tablet server per table id. The monitor currently lacks any metrics for scan severs that are similar to the current monitor tablet server metrics. There are metrics being emitted by scan servers that almost have enough information to construct a scan server metrics dashboard in an external metrics system, however the lack of table id information prevents having parity with the tablet server view in the monitor.

In general, if table ids were added to some subset of tablet server and scan server metrics then it could allow an external metrics system to achieve parity with the metrics offered by the monitor. The metrics in the monitor that do this are primarily concerned with table read, write, and compactions.

**Describe the solution you'd like**

For a subset of metrics related to reading and writing data tag them with table ids. This would like result in a `Map` in the code. For this map would need to be able to add new meters as new table ids are encountered and remove table ids that have not been used in a while. The meters in this map would have the table id tag.

**Describe alternatives you've considered**

Do not try to achieve feature parity in external metrics and custom monitor metrics.
