`always()` vs job cancellation

[dungdm93]

When a job received cancellation request, steps with condition always() still eligible to be run normally. However go context.Context() is canceled, so that steps will be failed.

Find the way handle this edge case properly.

actions/runner logic:

• the job status is marked as cancelled
• the step’s condition is re-evaluated
  • if fail, cancel the step
  • if true, the step is continue running

Normal steps and embedded steps, the step CancellationTokenSource is not linked to the parent/job token.
