Describe the bug

Warnings about MetricCollectingClientInterceptor and MetricCollectingServerInterceptor when using grpc and micrometer

Warnings:

• At least one unused gRPC client interceptor found: io.micrometer.core.instrument.binder.grpc.MetricCollectingClientInterceptor. If there are meant to be used globally, annotate them with @GlobalInterceptor.
• At least one unused gRPC interceptor found: io.micrometer.core.instrument.binder.grpc.MetricCollectingServerInterceptor. If there are meant to be used globally, annotate them with @GlobalInterceptor.

These warnings should be fixed or at least silenced using LogCleanupFilterBuildItem

Great catch!

Yes, we should exclude the metrics interceptors from the checked list.
