vmalert: datasource.roundDigits Parameter does not work

[gsakun]

Describe the bug

When I set -datasource.roundDigits="2",I expect the request to be sent to carry parameters round_digits=2. But it does not work

To Reproduce

cat <<EOF >> pod.yaml
groups:
  - name: cadvisor
    rules:
      - alert: ContainerMemoryUsage
        expr: '(sum(container_memory_working_set_bytes{name!=""}) BY (instance, name) / sum(container_spec_memory_limit_bytes > 0) BY (instance, name) * 100) > 80'
        for: 2m
        labels:
          severity: warning
        annotations:
          summary: Container Memory usage (instance {{ $labels.instance }})
          description: "Container Memory usage is above 80%\n  VALUE = {{ $value }}\n  LABELS = {{ $labels }}"
        debug: true
EOF
