Add request response logging and execution context

[ognjenkatic]

This PR adds a method to the workflow engine execution manager which adds request and response logging. The logging behavior logs request and response models, execution time, and execution context.
The execution context contains workflow id, name as well as task i and name. It should help us with filtering logs.

Added a pipeline builder, the ordering can still be bypassed with direct registrations. I would like to maybe disable this in the future and force all pipeline registrations through this method somehow.

builder.AddConductorSharp(
              baseUrl: configuration.GetValue<string>("Conductor:BaseUrl"),
              apiPath: configuration.GetValue<string>("Conductor:ApiUrl"),
              preventErrorOnBadRequest: configuration.GetValue<bool>("Conductor:PreventErrorOnBadRequest")
          )
          .AddExecutionManager(
              maxConcurrentWorkers: configuration.GetValue<int>("Conductor:MaxConcurrentWorkers"),
              sleepInterval: configuration.GetValue<int>("Conductor:SleepInterval"),
              longPollInterval: configuration.GetValue<int>("Conductor:LongPollInterval"),
              domain: configuration.GetValue<string>("Conductor:WorkerDomain")
          )
          .AddPipelines(pipelines =>
          {
              pipelines.AddRequestResponseLogging();
              pipelines.AddValidation();
          });

The old way is still supported, but will report a warning that the method has been deprecated
