Add custom format support to HttpLogging middleware

In production i want to log each http request in the format I select. With HttpLogging I can selected Headers and LoggingFields but I cannot format the result, which looks something like this.


I need to be able create single line logs and reorder logged properties

### Describe the solution you'd like

In `HttpLoggingOptions` I would like to be able to specify string format. It would look something like this:

```
builder.Services.AddHttpLogging(options =>
{
options.LogFormat = "Protocol {HttpProtocol} Scheme: {RequestScheme} \n Path: {Path}";
});

```
