Noise levels that rappor metrics can be collected with.  This list should be
kept in sync with NoiseLevel definitions in

<noise-levels>
<noise-level name="NO_NOISE">
  <summary>
    Adds no noise at all. Only use this for non-sensitive fields, and only for
    metrics from UMA opt-in users.
  </summary>
  <noise-values fake-prob="0.0" fake-one-prob="0.0" one-coin-prob="1.0"
      zero-coin-prob="0.0"/>

<noise-level name="NORMAL_NOISE">
  <summary>
    The most common amount of noise, suitable for most fields.

<noise-level name="SPARSE_NOISE">
  <summary>
    Reduced noise, suitable for metrics which receive limited reports (less than
    500,000 per day) or expect a highly skewed/sparse distribution over a wide
    set of domains. Approval from the Chrome Privacy and Rappor teams is
    required to implement a metric using this noise level.
