Monetization (MON-175): MonetizationModule - used Http::request() function

Generally speaking and if possible, we should be checking the current log level before dedicating any memory to a log call.  In this case, I think we should wrap the content of the block in 
```
if ( $log->getLogger()->isHandling( Logger::DEBUG ) ) {
   ...
}
``` 
or something similar.  If we don't check first we build a hash and concatenate strings for no reason.
