docs: Set manual overrides on the threshold (used for determining
          warning/critical status) a dict of limits. See
          :py:class:`~.AwsLimitChecker` for information on Warning and
          Critical thresholds.
  
          Dict is composed of service name keys (string) to dict of
          limit names (string), to dict of threshold specifications.
          Each threhold specification dict can contain keys 'warning'
          or 'critical', each having a value of a dict containing
          keys 'percent' or 'count', to an integer value.
  
          Example:
          ::
  
              {
                  'EC2': {
                      'SomeLimit': {
                          'warning': {
                              'percent': 80,
                              'count': 8,
                          },
                          'critical': {
                              'percent': 90,
                              'count': 9,
                          }
                      }
                  }
              }
