   * Retrieves an aggregated list of node groups. Note: use nodeGroups.listNodes

   *
   * @param string $project Project ID for this request.
   * @param array $optParams Optional parameters.
   *
   * @opt_param string filter A filter expression that filters resources listed in
   * the response. Most Compute resources support two types of filter expressions:
   * expressions that support regular expressions and expressions that follow API
   * improvement proposal AIP-160. If you want to use AIP-160, your expression
   * must specify the field name, an operator, and the value that you want to use
   * for filtering. The value must be a string, a number, or a boolean. The
   * 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`. The `:`
   * operator can be used with string fields to match substrings. For non-string
   * fields it is equivalent to the `=` operator. The `:*` comparison can be used
   * to test whether a key has been defined. For example, to find all objects with
   * `owner` label use: ``` labels.owner:* ``` 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) ``` If you want to use a
   * regular expression, use the `eq` (equal) or `ne` (not equal) operator against
   * a single un-parenthesized expression with or without quotes or against
   * multiple parenthesized expressions. Examples: `fieldname eq unquoted literal`
   * `fieldname eq 'single quoted literal'` `fieldname eq "double quoted literal"`
   * `(fieldname1 eq literal) (fieldname2 ne "literal")` The literal value is
   * interpreted as a regular expression using Google RE2 library syntax. The
   * literal value must match the entire field. For example, to filter for
   * instances that do not end with name "instance", you would use `name ne
   * .*instance`.
   * @opt_param bool includeAllScopes Indicates whether every visible scope for
   * each scope type (zone, region, global) should be included in the response.
   * For new resource types added after this field, the flag has no effect as new
   * resource types will always include every visible scope for each scope type in
   * response. For resource types which predate this field, if this flag is
   * omitted or false, only scopes of the scope types where the resource type is
   * expected to be found will be included.
   * @opt_param string 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`)
   * @opt_param string 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.
   * @opt_param string 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.
   * @opt_param bool returnPartialSuccess Opt-in for partial success behavior
   * which provides partial results in case of failure. The default value is
   * false.
