+Returns:
+  An object of the form:
+
+    { # An Operation resource, used to manage asynchronous API requests.
+    "targetId": "A String", # [Output Only] The unique target ID, which identifies a specific incarnation of the target resource.
+    "clientOperationId": "A String", # [Output Only] Reserved for future use.
+    "creationTimestamp": "A String", # [Deprecated] This field is deprecated.
+    "id": "A String", # [Output Only] The unique identifier for the resource. This identifier is defined by the server.
+    "zone": "A String", # [Output Only] The URL of the zone where the operation resides. Only available when performing per-zone operations.
+    "insertTime": "A String", # [Output Only] The time that this operation was requested. This value is in RFC3339 text format.
+    "operationType": "A String", # [Output Only] The type of operation, such as insert, update, or delete, and so on.
+    "httpErrorMessage": "A String", # [Output Only] If the operation fails, this field contains the HTTP error message that was returned, such as NOT FOUND.
+    "progress": 42, # [Output Only] An optional progress indicator that ranges from 0 to 100. There is no requirement that this be linear or support any granularity of operations. This should not be used to guess when the operation will be complete. This number should monotonically increase as the operation progresses.
+    "httpErrorStatusCode": 42, # [Output Only] If the operation fails, this field contains the HTTP error status code that was returned. For example, a 404 means the resource was not found.
+    "statusMessage": "A String", # [Output Only] An optional textual description of the current status of the operation.
+    "status": "A String", # [Output Only] The status of the operation, which can be one of the following: PENDING, RUNNING, or DONE.
+    "description": "A String", # [Output Only] A textual description of the operation, which is set when the operation is created.
+    "warnings": [ # [Output Only] If warning messages are generated during processing of the operation, this field will be populated.
+      {
+        "message": "A String", # [Output Only] A human-readable description of the warning code.
+        "code": "A String", # [Output Only] A warning code, if applicable. For example, Compute Engine returns NO_RESULTS_ON_PAGE if there are no results in the response.
+        "data": [ # [Output Only] Metadata about this warning in key: value format. For example:
+            # "data": [ { "key": "scope", "value": "zones/us-east1-d" }
+          {
+            "value": "A String", # [Output Only] A warning data value corresponding to the key.
+            "key": "A String", # [Output Only] A key that provides more detail on the warning being returned. For example, for warnings where there are no results in a list request for a particular zone, this key might be scope and the key value might be the zone name. Other examples might be a key indicating a deprecated resource and a suggested replacement, or a warning about invalid network settings (for example, if an instance attempts to perform IP forwarding but is not enabled for IP forwarding).
+          },
+        ],
+      },
+    ],
+    "user": "A String", # [Output Only] User who requested the operation, for example: user@example.com.
+    "startTime": "A String", # [Output Only] The time that this operation was started by the server. This value is in RFC3339 text format.
+    "kind": "compute#operation", # [Output Only] Type of the resource. Always compute#operation for Operation resources.
+    "name": "A String", # [Output Only] Name of the resource.
+    "region": "A String", # [Output Only] The URL of the region where the operation resides. Only available when performing regional operations.
+    "error": { # [Output Only] If errors are generated during processing of the operation, this field will be populated.
+      "errors": [ # [Output Only] The array of errors encountered while processing this operation.
+        {
+          "message": "A String", # [Output Only] An optional, human-readable error message.
+          "code": "A String", # [Output Only] The error type identifier for this error.
+          "location": "A String", # [Output Only] Indicates the field in the request that caused the error. This property is optional.
+        },
+      ],
+    },
+    "endTime": "A String", # [Output Only] The time that this operation was completed. This value is in RFC3339 text format.
+    "selfLink": "A String", # [Output Only] Server-defined URL for the resource.
+    "targetLink": "A String", # [Output Only] The URL of the resource that the operation modifies. For operations related to creating a snapshot, this points to the persistent disk that the snapshot was created from.
