Uniqueness of hostRequirements

[ryyakobe]

Description

It seems that OpenJobDescription doesn't specify that names for different hostRequirement should be unique. Python library also doesn't enforce name uniqueness, so it's possible to create a template with 2 different host requirements for the same step that have exactly the same name:

  hostRequirements:
    amounts:
    - name: amount.sameName
      min: 1
    - name: amount.sameName
      min: 4

This seems to be error-prone and I wonder if there is a use-case for allowing the same name for host requirements or maybe the specification should enforce name uniqueness?

This looks like a defect in the spec, and we should amend the existing version to fix that.
