YT-227 Fix submit LAVA task for smoke tests

  Smoke tests use a single type of test (boot.jinja2).
  However, some parameters need to be dynamic, such as device type.
  To address this, the `test-plan-args-var` introduced
  what allows environment variables with extra parameters to be used
  in the LAVA job generation script.
  The pipeline has been adjusted accordingly.
