[feature request] Filter out measurements based on tag value

[MhdTlb]

Package

OpenTelemetry

Is your feature request related to a problem?

When adding metrics for System.Net.Http, I noticed that we send measurements for OTLP Exporter requests as well. The tag for these measurements is server.port == 4137

What is the expected behavior?

It would be helpful to have a filter to ignore measurements with a given tag value.

Which alternative solutions or features have you considered?

There is no alternative solution

This shouldn't happen, the OTLP Exporter's traffic should be suppressed.
Can you please share a small sample app that reproduces this issue?

This is the expected behavior!

We don't have an ability inside SDK to filter based on tag value today. (But such capability might be available in Collector/ backends..)
