Feature/graphql logging (#674)

* Set graphql logs to error level

Set log level for loggers with names
 - ExecutionStrategy (spams logs with "... completing field ...")
 - notprivacysafe (logs every received request up to 4 times (received, parse, validate, execute))

* Extract logic to get logger for name into function

* Add function to set log level for a logger

* Add settings to enable graphql debug logging
