/**
* Encapsulates the overridable settings for a particular API call.
*
* ``CallOptions`` is an optional arg for all GAX API calls. It is used to
* configure the settings of a specific API call.
*
* When provided, its values override the GAX service defaults for that
* particular call.
*
* Typically the API clients will accept this as the second to the last
* argument. See the examples below.
* @typedef {Object} CallOptions
* @property {number=} timeout - The client-side timeout for API calls.
* @property {RetryOptions=} retry - determines whether and how to retry
* on transient errors. When set to null, the call will not retry.
* @property {boolean=} autoPaginate - If set to false and the call is
* configured for paged iteration, page unrolling is not performed, instead
* the callback will be called with the response object.
* @property {Object=} pageToken - If set and the call is configured for
* paged iteration, paged iteration is not performed and requested with this
* pageToken.
* @property {number} maxResults - If set and the call is configured for
* paged iteration, the call will stop when the number of response elements
* reaches to the specified size. By default, it will unroll the page to
* the end of the list.
* @property {boolean=} isBundling - If set to false and the call is configured
* for bundling, bundling is not performed.
* @property {BackoffSettings=} longrunning - BackoffSettings used for polling.
* @property {Function=} promise - A constructor for a promise that implements the ES6
* specification of promise which will be used to create promises. If not
* provided, native promises will be used.
* @example
* // suppress bundling for bundled method.
* api.bundlingMethod(
* param, {optParam: aValue, isBundling: false}, function(err, response) {
* // handle response.
* });
* @example
* // suppress streaming for page-streaming method.
* api.pageStreamingMethod(
* param, {optParam: aValue, autoPaginate: false}, function(err, page) {
* // not returning a stream, but callback is called with the paged response.
