Some services utilize numerous metadata addresses that exceed OpenTelemetry cardinality limits. To address this, IdentityModel should capture only the domain name rather than the complete metadata address, in success cases.

Example:

Instead of reporting https://login.microsoftonline.com/common/v2.0/.well-known/openid-configuration, report only microsoftonline.com

Since this represents a breaking behavioral change, IdentityModel should provide an AppContext switch to allow reverting to the previous behavior.
