ODLUX DB API Extension for Userdata

To be able to save user-specific data, such as settings for the NetworkMap (customization options) or the dashboard, the data-provider (Data-Provider) should be extended.

Goal:

• Provide a function to GET settings data by username
• Provide a function to POST / (PUT / PATCH?) settings data for a specific user
• Provide a function to DELETE settings data of a specific user

Restriction:

• username must be unique

Characteristics:

• Additional API on "/data-provider:userdata"
• Create a settings entry in the database if none exists
• Delivers back all settings of a user
• Updates the settings of a user 
• Can delete (reset) settings of a user

 Open Questions:

• when should the initial settings entry of a user be created? When settings are updated / saved for the first time?
• Use PUT or PATCH for updating entries? (settings may grow over time, eg. dashboard, networkmap, ...) Should the entire settings object be send or only a partial one?
• If we use PUT, do we need POST?
• Should settings be queryable by section? ( eg. dashboard, networkmap, ...)

Extension of data-provider

Example settings data of a user

{
    "networkMap":{
        "startupPosition": {"lat": 52.5095, "lon":13.3290, "zoom": 10},
        "tileOpacity": 90,
        "styling":{
            "theme": "light"
        }
    }
}

Note: settings data currently subject to change, note will be deleted once finalized
