Distributed operation with the PKCS library

As a developer I want to know how my application will react when a single HSM in my cluster stops operating. A sample that provides help with detecting and responding to cluster failures would be nice.

This should be similar to the [JCE sample](https://github.com/aws-samples/aws-cloudhsm-jce-examples/blob/master/src/main/java/com/amazonaws/cloudhsm/examples/ClientFailureRunner.java) in our other repo.

Start by reviewing the existing PKCS#11 examples in this repository and compare them with the referenced JCE ClientFailureRunner.java sample. Define the sample's expected behavior when one HSM in the cluster stops operating, then verify that it demonstrates detecting and responding to that failure.
