RFC006 contact information better distinction between phone numbers

[stevenvegt]

There may be high and low prio problems. So perhaps add a phone number for emergency and for normal priority:

    ContactInformation:
      type: object
      description: A set of contact information entries
      required:
        - emergencyPhone
        - supportEmail
      properties:
        emergencyPhone:
          type: string
          description: 24/7 available support phone number in case of emergency
        supportPhone:
          type: string
          description: phoneNumber for normal priority support
        supportEmail:
          type: string
          description: email address for normal priority support

I do not think there should be an emergency telephone number, simply because there shouldn't be emergencies where one node can be affected by the other.

This might follow from the the Minimal Viable Governance in which we can add sections about support and SLAs.
