            "historySetting": {

Mandatory:

                "storage": "fs",

Optional:

                "size": 4032,
                "path": "/place/to/store/my/persistence/"

"size" default: 4032
"path" default: .homebridge folder of the user or the given homebridge -U location

Google Drive persistence:

            "historySetting": {

Mandatory:

                "storage": "googleDrive",

Optional:

                "size": 4032,
                "folder": "fakegato",

For the setup of Google Drive, please follow the Google Drive Quickstart for Node.js instructions from https://developers.google.com/drive/v3/web/quickstart/nodejs, except for these changes:

In Step 1-h the working directory should be the .homebridge directory
Skip Step 2 and 3
In step 4, use the quickstartGoogleDrive.js included with this module. You need to run the command from fakegato-history directory. Then just follow steps a to c.
