     * @param {string} [options.credentials.client_email]
     * @param {string} [options.credentials.private_key]
     * @param {string} [options.email] - Account email address. Required when
     *     using a .pem or .p12 keyFilename.
     * @param {string} [options.keyFilename] - Full path to the a .json, .pem, or
     *     .p12 key downloaded from the Google Developers Console. If you provide
     *     a path to a JSON file, the projectId option below is not necessary.

     * @param {number} [options.port] - The port on which to connect to
     *     the remote host.
     * @param {string} [options.projectId] - The project ID from the Google
     *     Developer's Console, e.g. 'grape-spaceship-123'. We will also check
     *     the environment variable GCLOUD_PROJECT for your project ID. If your

     *     {@link https://developers.google.com/identity/protocols/application-default-credentials Application Default Credentials},

     *     API remote host.
     * @param {gax.ClientConfig} [options.clientConfig] - Client configuration override.
     *     Follows the structure of {@link gapicConfig}.
     * @param {boolean} [options.fallback] - Use HTTP fallback mode.
     *     In fallback mode, a special browser-compatible transport implementation is used
     *     instead of gRPC transport. In browser context (if the `window` object is defined)
     *     the fallback mode is enabled automatically; set `options.fallback` to `false`
     *     if you need to override this behavior.

     * Equivalent to `method.name.toCamelCase()`, but returns a NodeJS Stream object.
     * @param {Object} request
     *   The request object that will be sent.
     * @param {string} request.filter
     *   A filter expression that filters resources listed in the response. The expression must specify the field name, a comparison operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The comparison operator must be either `=`, `!=`, `>`, or `<`.
     *
     *   For example, if you are filtering Compute Engine instances, you can exclude instances named `example-instance` by specifying `name != example-instance`.
     *
     *   You can also filter nested fields. For example, you could specify `scheduling.automaticRestart = false` to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on resource labels.
     *
     *   To filter on multiple expressions, provide each separate expression within parentheses. For example: ``` (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake") ``` By default, each expression is an `AND` expression. However, you can include `AND` and `OR` expressions explicitly. For example: ``` (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) ```
     * @param {number} request.maxResults
     *   The maximum number of results per page that should be returned. If the number of available results is larger than `maxResults`, Compute Engine returns a `nextPageToken` that can be used to get the next page of results in subsequent list requests. Acceptable values are `0` to `500`, inclusive. (Default: `500`)
     * @param {string} request.orderBy
     *   Sorts list results by a certain order. By default, results are returned in alphanumerical order based on the resource name.
     *
     *   You can also sort results in descending order based on the creation timestamp using `orderBy="creationTimestamp desc"`. This sorts results based on the `creationTimestamp` field in reverse chronological order (newest result first). Use this to sort resources like operations so that the newest operation is returned first.
     *
     *   Currently, only sorting by `name` or `creationTimestamp desc` is supported.
     * @param {string} request.pageToken
     *   Specifies a page token to use. Set `pageToken` to the `nextPageToken` returned by a previous list request to get the next page of results.
     * @param {string} request.project
     *   Project ID for this request.
     * @param {string} request.region
     *   Name of the region for this request.
     * @param {boolean} request.returnPartialSuccess
     *   Opt-in for partial success behavior which provides partial results in case of failure. The default value is false.
     * @param {object} [options]
     *   Call options. See {@link https://googleapis.dev/nodejs/google-gax/latest/interfaces/CallOptions.html|CallOptions} for more details.
     * @returns {Stream}
     *   An object stream which emits an object representing [Operation]{@link google.cloud.compute.v1.Operation} on 'data' event.
     *   The client library will perform auto-pagination by default: it will call the API as many
     *   times as needed. Note that it can affect your quota.
     *   We recommend using `listAsync()`
     *   method described below for async iteration which you can stop as needed.
     *   Please see the
     *   [documentation](https://github.com/googleapis/gax-nodejs/blob/master/client-libraries.md#auto-pagination)
     *   for more details and examples.
