XD-1670: NPE when a container departs

When a container departs the cluster an attempt is made to
redeploy any modules it was running. However the stream
may have been destroyed or undeployed by the time the container's
ephemeral node goes away.

This fix will ignore modules for streams that don't exist
or aren't deployed.

Jobs aren't handled in this fix; they will be addressed
as part of https://jira.spring.io/browse/XD-1548.

XD-1659 Hdfs Acceptance Tests

- hdfs Acc test will wait for file/dir to be created.

  We identified that on a fresh deployment of XD it takes longer for the hdfs to deploy.  So we give it up to 10 seconds to see if the hdfs created the directory before beginning the test.

- waitForPath now throws IllegalStateException instead of eating the Interrupted Exception.

  Also updated the test to use the results from the waitForPath in the assertTrue to determine if the directory and file exist.
