Title: Don't try to log when there is no logger

If you have a high amount of requests (for instance on a deeply nested SOAP API) the logger starts to be a performance bottleneck. This pull-request enable you to set it to nil so it won't try to log and therefore will be faster.

```ruby
VCR.configure do |c|
c.debug_logger = nil
end
```
