TTPForge: Add variable passing between steps (#535)

Summary:
Pull Request resolved: https://github.com/facebookincubator/TTPForge/pull/535

Create the ability to dynamically set variables based on step outputs and then use them in subsequent steps.  This is achieved via two large changes:
- All steps take an `outputvar` value, and each step manually defines how it sets this value.  Steps where it doesn't make sense to have an output variable just do nothing with this value.
  - Inline step pipes any stdout output to a variable
  - HTTPRequest step pipes response body (or regex result of response body if set) to a variable
  - FetchURI step pipes the entire content output to a variable
  - All other steps do not currently define an output
- All steps now do a second templating step at step load time using these tags `{[{ ... }]}`. All steps now have a Template method, which each step needs to define to manually specify which variables will be templated.  We do this because TTPForge by default only templates once before loading the YAML.
