docs: Gets the maxCpc value for this KeywordEstimateRequest.
  
  @return maxCpc   * The max CPC bid for this keyword.
  
  In general, the {@code maxCpc} of a {@link KeywordEstimateRequest}
  is
  optional, since there is usually another {@code
  maxCpc} that can be used,
  such as the {@code maxCpc} on an existing keyword,
  an existing or
  overriding {@code maxCpc} of containing {@link
  AdGroupEstimateRequest}.
  However, if there is no backup value of {@code
  maxCpc} anywhere along the
  line, you must provide a value for {@code maxCpc}
  in
  {@link KeywordEstimateRequest}. This would happen,
  for example, if the
  {@link KeywordEstimateRequest} is for a new keyword.
