XD-1161 Fix hdfs writing not to overwrite when stream restarted (wait SHDP PR#39)

- Depends on SHDP-243 and its PR 39
- Naming strategies are now ordered so that we can have base file name
  and suffix before and after rolling part. i.e. data-1.txt,
  data-2.txt, etc.
- Added missing default options to hdfs.properties and changed
  hdfs.xml accordingly
- Forcing new directory for every stream is done in naming by using
  "/${xd.stream.name}/${fileName:${xd.stream.name}}". afaik, default
  value for with variable can't be yet defined in hdfs.properties.
