Install any available upgrades for an extension.
If it is a minor upgrade, this process will recreate the extension using the same settings it currently has.
This operation will download the latest updates for this version of the extension from the extension store.
The body parameters state, files and/or ip_address, if non-null, can be used to change the current settings of the extension. If these parameters are not supplied or set to null the existing settings will be used.
The query parameter sync=true may be provided to make this a synchronous operation. In this case, the operation produces JSON status updates during the operation using HTTP chunked transfer encoding.
The default is asynchronous operation. To check on the progress of the operation, use GET /extension/instance/{id}. The install_time property will be updated when the extension is upgraded.
