Arvados

This was observed on ce8i5 as part of keepstore-on-the-compute-node testing in #18320 (the `keepstore.txt` file listed the about below as warnings). We reproduced it with `arvados-server config-dump | arvados-server config-check`:

All of these warnings are wrong. The keys are not invalid, and none of the InstanceType definitions have a `Name` or `Scratch` field defined.

Note that running `arvados-server config-check` by itself produces no output, as expected. The problem must be in the output generated by config-dump, e.g. this is the `InstanceTypes` section:

    InstanceTypes:
      a1v2:
        AddedScratch: 0
        IncludedScratch: 10000000000
        Name: a1v2
        Preemptible: false
        Price: 0.043
        ProviderType: Standard_A1_v2
        RAM: 2147483648
        Scratch: 10000000000
        VCPUs: 1
      a2v2:
        AddedScratch: 0
        IncludedScratch: 20000000000
        Name: a2v2
        Preemptible: false
        Price: 0.091
        ProviderType: Standard_A2_v2
        RAM: 4294967296
        Scratch: 20000000000
        VCPUs: 2
...

The actual config file has:

    InstanceTypes:
      a1v2:
        ProviderType: Standard_A1_v2
        VCPUs: 1
        RAM: 2GiB
        IncludedScratch: 10GB
        Price: 0.043
      a2v2:
        ProviderType: Standard_A2_v2
        VCPUs: 2
        RAM: 4GiB
        IncludedScratch: 20GB
        Price: 0.091
...

Here's the `config-dump` output for the other keys that generate warnings:

      ManagedProperties:
        responsible_person_uuid:
          Function: original_owner
          Protected: true
          Value: null
...
      NewInactiveUserNotificationRecipients:
        REDACTED@curii.com: {}
      NewUserNotificationRecipients:
        REDACTED@curii.com: {}
