/**
 *  The Cloud Firestore Admin API.
 *
 *  This API provides several administrative services for Cloud Firestore.
 *
 *  Project, Database, Namespace, Collection, Collection Group, and Document are
 *  used as defined in the Google Cloud Firestore API.
 *
 *  Operation: An Operation represents work being performed in the background.
 *
 *  The index service manages Cloud Firestore indexes.
 *
 *  Index creation is performed asynchronously.
 *  An Operation resource is created for each such asynchronous operation.
 *  The state of the operation (including any errors encountered)
 *  may be queried via the Operation resource.
 *
 *  The Operations collection provides a record of actions performed for the
 *  specified Project (including any Operations in progress). Operations are not
 *  created directly but through calls on other collections or resources.
 *
 *  An Operation that is done may be deleted so that it is no longer listed as
 *  part of the Operation collection. Operations are garbage collected after
 *  30 days. By default, ListOperations will only return in progress and failed
 *  operations. To list completed operation, issue a ListOperations request with
 *  the filter `done: true`.
 *
 *  Operations are created by service `FirestoreAdmin`, but are accessed via
 *  service `google.longrunning.Operations`.

   * @param {string} [options.credentials.client_email]
   * @param {string} [options.credentials.private_key]
   * @param {string} [options.email] - Account email address. Required when

   * @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.
   *     NOTE: .pem and .p12 require you to specify options.email as well.

   *     the remote host.
   * @param {string} [options.projectId] - The project ID from the Google
