Replace DiagnosticListener in Services.Remoting with ActivitySource for Activity creation

[AndreyTretyak]

DiagnosticListener that creates Activity for remoting requests need to be replaced with ActivitySource
We would probably need to keep the listener for Exception reporting for now.

Omex/src/Extensions/Services.Remoting/Internal/Diagnostics.cs

Line 29 in 0ae2c9d

public static Activity? CreateAndStartActivity(this DiagnosticListener listener, string name, string parentId = "")
