Square complexity in Signal when using AdviseOnce pattern

[nerzhulart]

If we call CurrentClientLifetime N times and then terminate lifetime of LocalCodeWithMeClientManager which removes a client we get a N^2 calls of ValueLifetime.ClearValueIfNotAlive

    public static Lifetime CurrentClientLifetime(this ICodeWithMeClientManager manager)
    {
      var clientId = ClientId.Current;
      var lifetimeDefinition = Lifetime.Define(Lifetime.Eternal, $"Lifetime of {clientId}");
      Log.Assert(manager.Clients.Contains(clientId), $"Client manager doesn't know about {clientId}");
      var lifetime = lifetimeDefinition.Lifetime;
      manager.Clients.Advise(lifetime, (addRemove, triggeredId) =>
      {
        if (addRemove == AddRemove.Remove && triggeredId == clientId)
        {
          lifetimeDefinition.Terminate();
        }
      });
      return lifetime;
    }
....
  public class LocalCodeWithMeClientManager : ICodeWithMeClientManager
  {
    public LocalCodeWithMeClientManager(Lifetime lifetime)
    {
      Clients.Add(ClientId.LocalId);
      lifetime.OnTermination(() => Clients.Remove(ClientId.LocalId));
    }

    public IViewableSet<ClientId> Clients { get; } = new ViewableSet<ClientId>();
  }
