Initial support windows

[cosmo0920]

I've written patches to support Windows!

Let's cut out Windows support feature!!!

For PowerShell config is like this:

out:
  type: command
  command: ${input} > task.${Env:INDEX}.${Env:SEQID}.csv
  formatter:
    type: csv

It works as below:

It worked well on my windows environment.
