Connector SPI should have protocol for cancelling operations
------------------------------------------------------------

                 Key: DNA-217
                 URL: https://jira.jboss.org/jira/browse/DNA-217
             Project: DNA
          Issue Type: Task
          Components: Connectors, SPI
    Affects Versions: 0.2
            Reporter: Randall Hauch
            Assignee: Randall Hauch
             Fix For: 0.2

The Connector SPI needs a specific way for calls to the connector to be canceled.  Currently, most of the methods throw InterruptedException, which is a painful (and confusing) way to handle it.  This exception should be removed while the use of ProgressMonitor be added.  

Additionally, we may want to consider modifying the ProgressMonitor framework so that it's possible for it to threat Thread.interrupt() as a cancellation (whereby it would use that, in addition to the internal flag, to determine whether the monitor is canceled.  This may require an additional method whereby the code checking "isCanceled()" acknowledges that it is canceling what it's doing (so that the ProgressMonitor can call Thread.interrupted() to clear the interrupted state).
