CloudWatch SLI causes error when converting

[ian-bartholomew]

Summary

when unmarshaling CloudWatch data, the sequence nodes are getting improperly unmarshaled, causing an error when running olso convert

Steps to reproduce

Given file sli.yaml:

apiVersion: openslo/v1
kind: SLI
metadata:
  name: foo-sli
spec:
  description: string # optional up to 1050 characters
  thresholdMetric: 
    metricSource:
      metricSourceRef: foo-cloudwatch
      type: CloudWatch
      spec:
        metricName: 2xx
        namespace: CloudWatchSynthetics
        region: us-east-1
        stat: SampleCount
        dimensions:
          - name: following
            value: bar

run oslo convert -f sli.yaml -o nobl9

What is the current bug behavior?

This will cause an error

What is the expected correct behavior?

The yaml should be correctly parsed and the nobl9 yaml produced

Seeing that this might not have solved for all use cases so reopening
