Workflow variables

Registered by Renat Akhmerov

We need a new section in workflow definition where we could define a list of explicit workflow variables.

DSL Example:

workflows:
  my_wf:
    type: direct

    input:
    ...

    vars:
      var1: val1
      var2: val2

These variables should be accessible the same way as regular workflow context variables.
