XD-1520 Update ModuleOptions stream name defaults

- Fix Module options that use stream name as the default value
  - Add ${xd.stream.name} as the default value in appropriate
module options POJO and module options properties
  - This will allow `module info` command to display the default values
with ${xd.stream.name} wherever stream name is used

Following modules are fixed:
File Sink
Gemfire sinks
Aggregator
File source
Metrics
HDFS dataset
Hdfs + move into own dir
Post
Tail
JMS
