Dataflow annotation

[mtitov]

• Provide API to annotate tasks with dataflow (tasks inputs/outputs) - proposal: https://gist.github.com/mtitov/7b04f84a21ddd0557c60ad48ec16a288
• Extend task metadata with process id (will be used in conjunction with Darshan to automate dataflow annotation)
• Enable automatic dataflow annotation using Darshan I/O characterization tool

TODO:

• Check validation mechanisms for file names - having " a module we can use to test file names with a variety of non alphanumericals" (link to the original comment)
• Review file name format
