Implement/Convert existing EventCounters to Metrics

[samsp-msft]

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

@samsp-msft do we have issues in the appropriate repo's tracking the requested work?

[davidfowl]

We should open issues and tag the appropriate teams on the right repos. We'll need to flesh out each of the issues with what each counter definition looks like and what dimensions it should have.

Not yet. We should figure out what the guidance is before we explode out the work. For example, what dimensions should we the metrics use. AFAIK both dimension key & value counts should be small - how small is the question.
