Shopify Connector Installation & Setup

To connect IMan to a Shopify store, create an app for IMan in Shopify's Dev Dashboard, then give IMan the app's credentials in a System Connector.

1. Installation: check that IMan has loaded the Shopify connector.
2. Shopify Setup: create the app, give it the access scopes, install it on the store, and copy its Client ID and Secret.
3. IMan System Connector Setup: create the System Connector with the store's ID and the app's credentials.
