Is AdaptiveHandler used?

[nikophil]

Hello,

it seems that the service \Ekino\NewRelicBundle\Logging\AdaptiveHandler is never used.
I can't find any configuration or DI stuff where we use this class instead of \Monolog\Handler\NewRelicHandler.

Moreover, if I activate monolog logging in local (where php new_relic extension is not loaded, I got this error, from NewRelicHandler: 'The newrelic PHP extension is required to use the NewRelicHandler'

do you want that a provide a PR for using it? or you'd rather delete the class?
