Allow to dispose linked resources on pipeline disposal

[martintmk]

Details on the issue fix or feature implementation

Allows disposal of resources attached to the pipeline or to attach any cleanup actions:

var provider = new ServiceCollection()
    .AddResiliencePipeline("my-pipeline", (builder, context) =>
    {
        var limiter = new ConcurrencyLimiter(new ConcurrencyLimiterOptions
        {
            PermitLimit = 1,
            QueueLimit = 1
        });

        builder.AddRateLimiter(new RateLimiterStrategyOptions
        {
            RateLimiter = args => limiter.AcquireAsync(1, args.Context.CancellationToken)
        });

        // when the pipeline instance is disposed, limiter is disposed too
        context.OnPipelineDisposed(() => limiter.Dispose());
    });

This is not inclusive to rate limiters as any disposable resource created when configuring the pipeline can be now freed after the pipeline is disposed. This prevents memory leaks and improves the performance.
