Streams 296
Quick fix to ensure documents are not discarded by ESPersistWriter before
they are recieved as WebHdfsPersistReader terminates.
These changes ensure ElasticsearchHdfsIT in
incubator-streams-examples/elasticsearch-hdfs is able to pass.

added mandatory pauses as providers and persist writers terminate to
mitigate race condition causing document loss

switch to use uninterruptibles for thread sleep, and add additional pausing
to tasks experiencing race conditions on interrupts.
this is not the ideal fix to the root cause which I believe to be sloppy
thread management throughout streams-runtime-local, but it is sufficient to
ensure the integration test proposed for
incubator-streams-examples/elasticsearch-hdfs passes.
