Description

In HDFS-7546 we added a hdfs-default.xml property to bring back the regular behaviour of trusting all principals (as was the case before HADOOP-9789). However, the change only targeted HDFS users and also only those that used the default-loading mechanism of Configuration class (i.e. not new Configuration(false) users).

I'd like to propose adding the same default to the generic RPC client code also, so the default affects all form of clients equally.
