listing EC2 inventory

fix JSON extra vars quotation.

Loading the default variables in _build_role_dependencies() lead to
a side-effect where those variables were over-riding inventory variables.

* Default variables are now fed directly into roles, just like the
  other variables, so that roles see their unique values rather
  than those set at the global level.

* Role dependency duplicates are now determined by checking the params used
  when specifying them as dependencies rather than just on the name of the
  role. For example, the following would be included twice without having
  to specify "allow_duplicates: true":

  dependencies:
  - { role: foo, x: 1 }
  - { role: foo, x: 2 }
