The System.Diagnostics.Metrics api was added with support for dimensioned metrics, but it doesn't seem to have been utilized much by the framework. We should have an effort to go through the framework and update usage of EventCounter to Meter, adding dimensions where applicable.

The main areas that should be considered are:

• Http
• Crypto?
• Disk IO?

Tracking work in external repos:

• Modify EventCounter usage to support the new metric APIs as well aspnetcore#33387
