BackendListener should not be aware of a particular implementation of BackendListenerClient : GraphiteBackendListenerClient

@pmouawad ([Bug 59241](https://bz.apache.org/bugzilla//show_bug.cgi?id=59241&redirect=false)):
Related to fix of https://github.com/apache/jmeter/issues/3901 in JMeter 3.0, BackendListener now references GraphiteBackendListenerClient:

public void setArguments(Arguments args) {
// https://github.com/apache/jmeter/issues/3901 - don't save new default argument
args.removeArgument(GraphiteBackendListenerClient.USE_REGEXP_FOR_SAMPLERS_LIST,
GraphiteBackendListenerClient.USE_REGEXP_FOR_SAMPLERS_LIST_DEFAULT);
setProperty(new TestElementProperty(ARGUMENTS, args));
}
