Move the named pipe no bootstrap test to a separate qa module (elastic/elasticsearch#769)

This matches the way tests that need to run without an Elasticsearch
bootstrap are run in core Elasticsearch.  This should make merging to
x-pack easier.

Note that the no bootstrap tests now run after the integration tests, but
this doesn't really matter.
