Component Execution Status

###Example usage with Serilog:

using PipelineFramework.Abstractions;
using Serilog;
using System.Diagnostics.CodeAnalysis;
using System.Threading.Tasks;

namespace PipelineFramework.Core.Examples
{
    [ExcludeFromCodeCoverage]
    public class ExecutionStatusReceiver : IAsyncPipelineComponentExecutionStatusReceiver
    {
        private readonly ILogger _logger;

        public ExecutionStatusReceiver(ILogger logger)
        {
            _logger = logger;
        }

        public Task ReceiveExecutionStartingAsync(PipelineComponentExecutionStartingInfo executionInfo)
        {
            var logger = EnrichLogger(_logger, executionInfo.Payload);
            logger.Information(
                "Component '{PipelineComponentName}' execution starting at {TimeStamp}",
                executionInfo.PipelineComponentName,
                executionInfo.TimeStamp.ToShortTimeString());

            return Task.CompletedTask;
        }

        public Task ReceiveExecutionCompletedAsync(PipelineComponentExecutionCompletedInfo executionInfo)
        {
            var logger = EnrichLogger(_logger, executionInfo.Payload);
            if (executionInfo.Exception == null)
            {
                logger.Information(
                       "Component '{PipelineComponentName}' execution completed at {TimeStamp}.  Duration: {TotalMilliseconds}ms",
                       executionInfo.PipelineComponentName,
                       executionInfo.TimeStamp.ToShortTimeString(),
                       executionInfo.ExecutionTime.TotalMilliseconds);
            }
            else
            {
                logger.Error(
                    executionInfo.Exception,
                    "Component '{PipelineComponentName}' execution failed at {TimeStamp}.  Duration: {TotalMilliseconds}ms",
                    executionInfo.PipelineComponentName,
                    executionInfo.TimeStamp.ToShortTimeString(),
                    executionInfo.ExecutionTime.TotalMilliseconds);
            }

            return Task.CompletedTask;
        }

        private static ILogger EnrichLogger(ILogger logger, object payload) =>
            payload is ExamplePipelinePayload p
                ? logger.ForContext("FooKey", p.FooKey).ForContext("Result", p.Result)
                : logger;
    }
